* Object.extendDeep
* Object.descriptor.binder
* Object.safeTraverse
* RegExp.validRegExp

* Accapt any callable object as callback in Object.filter, mapKeys and map
* Convention cleanup

v0.9.0  --  2012.09.13
We're getting to real solid API

Removed:
* Function#memoize - it's grown up to be external package, to be soon published
  as 'memoizee'
* String.guid - it doesn't fit es5-ext (extensions) concept, will be provided as
  external package
# Function.arguments - obsolete
# Function.context - obsolete
# Function#flip - not readable when used, so it was never used
# Object.clone - obsolete and confusing

Added:
* String#camelToHyphen - String format convertion

Renamed:
* String#dashToCamelCase -> String#hyphenToCamel

Fixes:
* Object.isObject - Quote names in literals that match reserved keywords
  (older implementations crashed on that)
* String#repeat - Do not accept negative values (coerce them to 1)

Improvements:
* Array#remove - Accepts many arguments, we can now remove many values at once
* Object iterators (forEach, map, some) - Compare function invoked with scope
  object bound to this
* Function#curry - Algorithm cleanup
* Object.isCopy - Support for all types, not just plain objects
* Object.isPlainObject - Support for cross-frame objects
* Do not memoize any of the functions, it shouldn't be decided internally
* Remove Object.freeze calls in reserved, it's not up to convention
* Improved documentation
* Better linting (hard-core approach using both JSLint mod and JSHint)
* Optional arguments are now documented in funtions signature

v0.8.2  --  2012.06.22
Fix errors in Array's intersection and exclusion methods, related to improper
usage of contains method

v0.8.1  --  2012.06.13
Reorganized internal logic of Function.prototype.memoize. So it's more safe now
and clears cache properly. Additionally preventCache option was provided.

v0.8.0  --  2012.05.28
Again, major overhaul. Probably last experimental stuff was trashed, all API
looks more like standard extensions now.

Changes:
* Turn all Object.prototype extensions into functions and move them to Object
namespace. We learned that extending Object.prototype is bad idea in any case.
* Rename Function.prototype.curry into Function.prototype.partial. This function
  is really doing partial application while currying is slightly different
  concept.
* Convert Function.prototype.ncurry to new implementation of
  Function.prototype.curry, it now serves real curry concept additionaly it
  covers use cases for aritize and hold, which were removed.
* Rename Array's peek to last, and provide support for sparse arrays in it
* Rename Date's monthDaysCount into daysInMonth
* Simplify object iterators, now order of iteration can be configured with just
  compareFn argument (no extra byKeys option)
* Rename Object.isDuplicate to Object.isCopy
* Rename Object.isEqual to Object.is which is compatible with future 'is'
  keyword
* Function.memoize is now Function.prototype.memoize. Additionally clear cache
  functionality is added, and access to original arguments object.
* Rename validation functions: assertNotNull to validValue, assertCallable to
  validCallable. validValue was moved to Object namespace. On success they now
  return validated value instead of true, it supports better composition.
  Additionally created Date.validDate and Error.validError
* All documentation is now held in README.md not in code files.
* Move guid to String namespace. All guids now start with numbers.
* Array.generate: fill argument is now optional
* Object.toArray is now Array.from (as new ES6 specification draft suggests)
* All methods that rely on indexOf or lastIndexOf, now rely on egal (Object.is)
  versions of them (eIndexOf, eLastIndexOf)
* Turn all get* functions that returned methods into actuall methods (get*
  functionality can still be achieved with help of Function.prototype.partial).
  So: Date.getFormat is now Date.prototype.format,
  Number.getPad is now Number.prototype.pad,
  String.getFormat is now String.prototype.format,
  String.getIndent is now String.prototype.indent,
  String.getPad is now String.prototype.pad
* Refactored Object.descriptor, it is now just two functions, main one and
  main.gs, main is for describing values, and gs for describing getters and
  setters. Configuration is passed with first argument as string e.g. 'ce' for
  configurable and enumerable. If no configuration string is provided then by
  default it returns configurable and writable but not enumerable for value or
  configurable but not enumerable for getter/setter
* Function.prototype.silent now returns prepared function (it was
  expected to be fixed for 0.7)
* Reserved keywords map (reserved) is now array not hash.
* Object.merge is now Object.extend (while former Object.extend was completely
  removed) - 'extend' implies that we change object, not creating new one (as
  'merge' may imply). Similarily Object.mergeProperties was renamed to
  Object.extendProperties
* Position argument support in Array.prototype.contains and
  String.prototype.contains (so it follows ES6 specification draft)
* endPosition argument support in String.prototype.endsWith and fromPosition
  argument support in String.prototype.startsWith (so it follows ES6
  specification draft)
* Better and cleaner String.prototype.indent implementation. No default value
  for indent string argument, optional nest value (defaults to 1), remove
  nostart argument
* Correct length values for most methods (so they reflect length of similar
  methods in standard)
* Length argument is now optional in number and string pad methods.
* Improve arguments validation in general, so it adheres to standard conventions
* Fixed format of package.json

Removed methods and functions:
* Object.prototype.slice - Object is not ordered collection, so slice doesn't
  make sense.
* Function's rcurry, rncurry, s - too cumbersome for JS, not many use cases for
  that
* Function.prototype.aritize and Function.prototype.hold - same functionality
  can be achieved with new Function.prototype.curry
* Function.prototype.log - provided more generic Function.prototype.wrap for
  same use case
* getNextIdGenerator - no use case for that (String.guid should be used if
  needed)
* Object.toObject - Can be now acheived with Object(validValue(x))
* Array.prototype.someValue - no real use case (personally used once and
  case was already controversial)
* Date.prototype.duration - moved to external package
* Number.getAutoincrement - No real use case
* Object.prototype.extend, Object.prototype.override,
  Object.prototype.plainCreate, Object.prototype.plainExtend - It was probably
  too complex, same should be achieved just with Object.create,
  Object.descriptor and by saving references to super methods in local scope.
* Object.getCompareBy - Functions should be created individually for each use
  case
* Object.get, Object.getSet, Object.set, Object.unset - Not many use cases and
  same can be easily achieved with simple inline function
* String.getPrefixWith - Not real use case for something that can be easily
  achieved with '+' operator
* Object.isPrimitive - It's just negation of Object.isObject
* Number.prototype.isLess, Number.prototype.isLessOrEqual - they shouldn't be in
  Number namespace and should rather be addressed with simple inline functions.
* Number.prototype.subtract - Should rather be addressed with simple inline
  function

New methods and functions:
* Array.prototype.lastIndex - Returns last declared index in array
* String.prototype.last - last for strings
* Function.prototype.wrap - Wrap function with other, it allows to specify
  before and after behavior transform return value or prevent original function
  from being called.
* Math.sign - Returns sign of a number (already in ES6 specification draft)
* Number.toInt - Converts value to integer (already in ES6 specification draft)
* Number.isNaN - Returns true if value is NaN (already in ES6 specification
  draft)
* Number.toUint - Converts value to unsigned integer
* Number.toUint32 - Converts value to 32bit unsigned integer
* Array.prototype.eIndexOf, eLastIndexOf - Egal version (that uses Object.is) of
  standard methods (all methods that were using native indexOf or lastIndexOf
  now uses eIndexOf and elastIndexOf respectively)
* Array.of - as it's specified for ES6

Fixes:
* Fixed binarySearch so it always returns valid list index
* Object.isList - it failed on lists that are callable (e.g. NodeList in Nitro
  engine)
* Object.map now supports third argument for callback

v0.7.1  --  2012.01.05
New methods:
* Array.prototype.firstIndex - returns first valid index of array (for
	sparse arrays it may not be '0'

Improvements:
* Array.prototype.first - now returns value for index returned by firstIndex
* Object.prototype.mapToArray - can be called without callback, then array of
	key-value pairs is returned

Fixes
* Array.prototype.forEachRight, object's length read through UInt32 conversion

v0.7.0  --  2011.12.27
Major update.
Stepped back from experimental ideas and introduced more standard approach
taking example from how ES5 methods and functions are designed. One exceptions
is that, we don’t refrain from declaring methods for Object.prototype - it’s up
to developer whether how he decides to use it in his context (as function or as
method).

In general:
* Removed any method 'functionalization' and functionalize method itself.
	es5-ext declares plain methods, which can be configured to work as functions
	with call.bind(method) - see documentation.
* Removed separation of Object methods for ES5 (with descriptors) and
	ES3 (plain) - we're following ES5 idea on that, some methods are intended just
	for enumerable properties and some are for all properties, all are declared
	for Object.prototype
* Removed separation of Array generic (collected in List folder) and not generic
	methods (collected in Array folder). Now all methods are generic and are in
	Array/prototype folder. This separation also meant, that methods in Array are
	usually destructive. We don’t do that separation now, there’s generally no use
	case for destructive iterators, we should be fine with one version of each
	method, (same as ES5 is fine with  e.g. one, non destructive 'filter' method)
* Folder structure resembles tree of native ES5 Objects
* All methods are written with ES5 conventions in mind, it means that most
	methods are generic and can be run on any object. In more detail:
	** Array.prototype and Object.prototype methods can be run on any object (any
		not null or undefined value),
	** Date.prototype methods should be called only on Date instances.
	** Function.prototype methods can be called on any callable objects (not
		necessarily functions)
	** Number.prototype & String.prototype methods can be called on any value, in
		case of Number it it’ll be degraded to number, in case of string it’ll be
		degraded to string.
* Travis CI support (only for Node v0.6 branch, as v0.4 has buggy V8 version)

Improvements for existing functions and methods:
* Function.memoize (was Function.cache) is now fully generic, can operate on any
	type of arguments and it’s NaN safe (all NaN objects are considered equal)
* Method properties passed to Object.prototype.extend or
	Object.prototype.override can aside of _super optionally take prototype object
	via _proto argument
* Object iterators: forEach, mapToArray and every can now iterate in specified
	order
* pluck, invoke and other functions that return reusable functions or methods
	have now their results memoized.

New methods:
* Global: assertNotNull, getNextIdGenerator, guid, isEqual, isPrimitive,
	toObject
* Array: generate
* Array.prototype: binarySearch, clear, contains, diff, exclusion, find, first,
	forEachRight, group, indexesOf, intersection, remove, someRight, someValue

* Function.prototype: not, silent
* Number: getAutoincrement, isNumber

* Object: assertCallable, descriptor (functions for clean descriptors),
	getCompareBy, isCallable, isObject
* Object.prototype: clone (real clone), compact, count, diff, empty,
	getPropertyNames, get, keyOf, mapKeys, override, plainCreate, plainExtend,
	slice, some, unset
* RegExp: isRegExp
* String: getPrefixWith, isString
* String.prototype: caseInsensitiveCompare, contains, isNumeric

	Object/plain/merge)
* Object/plain/setTrue -> now easily configurable by more universal
	Object.getSet(true)
