Message:

Final step in Random numbers is done ...

• requires CodePatterns 1.0.7.
• RandomNumberDistributionFactory and RandomNumberEngineFactory are now ManipulablePrototypeFactory's (and ...Engine and ..Distribution_Encapsulation are ManipulableClone's).
• new sets of manipulation parameters RandomNumberDistribution_Parameters and RandomNumberEngine_Parameters.
• added Query for RandomNumberDistribution_Parameters because GUI will need to change for specific parameters depending on selected distribution. ... actually, this happened accidentally and was an enormous amount of work ...
• added string parser for distribution parameters from CommandLine, TextUI and QtUI with boost::tokenizer.
• ValueStorage uses this parser for query and setting of CurrentValue.
• unit tests are working and are doing their job very well (found a bug with clone not using the distriubtion to clone's parameters).
• added PrototypeManipulationTest to engine and distribution factory unit test.
• regression tests with Undo/Redo are done.
• what's missing is an extension of the test of RandomNumberGeneratorFactory.
