### createIsATest

    public static java.lang.Object createIsATest(java.lang.String id)

  This returns an object which can be used to test if some other repository ID is an instance of this one.

  Examples:

       RepoIDHelper.createIsATest( "IDL:MyObj:1.0" ).equals(
               "IDL:MyObj:1.0" ) == true
