Bigger rewrite of RandomNumbers ... due to cloning of prototypes.

  • in order to copy the prototypes and not use the original instance, we have implemented a new pattern called "Creator" that wraps a templated class in a creation interface class such that this abstract class can instaniate the particular types (see here ​http://stackoverflow.com/questions/3506026/c-clone-abstract-base-class-without-meddling-with-derived). This is also wrapped up in ..._Creator.hpp files.
  • meanwhile we also tried to have factories for Engine and Distribution but this failed due to boost::variate_operator<> having to know the particular types of engine and distribution. One could go forth with some cast's but this is very unclean and not what we want. ... Downside is that we can't set global options for engines or distributions as of now.
  • For the moment Engine- and DistributionFactory both have a prototype table, i.e. the same wrapped ones as above, but they are not used for the GeneratorFactory.
  • Property mode set to 100644
