Name:

    testsuite::test_symmetric_connections - Tests that the functionality to create
      symmetric connections works properly.

Synopsis:

    (test_symmetric_connections) run -> NEST exits if test fails

Description:

      This test ensures that the functionality to create symmetric connections
      via flag "make_symmetric" works properly. It also ensures that the
      built-in property "requires_symmetric" for synapse models works properly.

      In more detail the test ensures that
     	- the "make_symmetric" flag works properly with one-to-one connection rule
     	- the usage of the "make_symmetric" flag with any other connections throws
      an NotImplemented exception
     	- synapse models that "require_symmetric" cannot be created without
      "make_symmetric" except for suitable uniform all-to-all connections
