Name:

    CreateRDV - Create a new random deviate generator

Synopsis:

      rngtype rdvfacttype	 CreateRDV -> rdvtype
      rngtype rdvfacttype paramdict CreateRDV -> rdvtype
      rngtype dict1	 CreateRDV -> dict2
      rngtype dict1 paramdict	 CreateRDV -> dict2

Examples:

      Create a generator for binomial numbers based on an MT19937 random
      number generator, set parameters to p=0.2 and n=10, and draw five numbers:

      SLI ] rngdict /MT19937 get 123456789 CreateRNG /rng Set
      SLI ] rng rdevdict /binomial get << /p 0.2 /n 10 >> CreateRDV /bino Set
      SLI ] bino 5 RandomArray ==
      [2 3 2 2 1]

Description:

      Create a new random deviate generator for a given distribution.  See
      rdevdict for the available distributions, and the documentation for
      the individual deviates (under rdevdict::*). The distribution instance
      can either be generated from a distribution implemented in C++
      represented by rdvfactype or a SLI implementation of a distribution
      represented by a dictionary. In the former case the return value is of
      rdvtype in the latter case a dictionary.

      If a paramdict is passed, it is used to set the parameters of the
      random deviate generator. Parameters can be inspected and changed with
      GetStatus/SetStatus where applicable.

Parameters:

      rngtype		- random generator as source of random numbers
      rdvfacttype	- distribution to draw from, from rdevdict
      paramdict  	- dictionary with distribution parameters
      rdvtype		- the initialized C++ object representing the distribution
      dict1		- dictionary used as a template to create the distribution
      dict2		- the cloned and initalized dictionary representing the distribution
