Refactoring of MMM framework to SimoxUtility: Added string helpers and conversion tools, a distinguishable color lookup table e.g. for creating graphs, a rapidxml wrapper for easier parsing of xml files and moved deprecated RobotPoseDiffIK from MMMTools to VirtualRobot

Use this to generate:
* boost lexical casts (to string, to enum)
* std::to_string
* operator<<

Also
* Move EnumNames to a subdir

* add template meta helpers for eigen
* add converter functions
* add periodic clamp
* move eigen subdir to shapes
* add tests
