Shogun slim

This is a rough sketch of things to do to get a more slim and easier maintainable Shogun. Every item has dependencies that need to be done first. Starting from leafs of this tree, we have an action list.

• Drop Parameter framework
• Drop Model-selection framework and/or move inside Shogun modules
• Drop GP-model selection (quite feasible)
• Drop SVM model selection, not necessary, see here
• Drop Serialisation.
• Drop integration tests * Clean up Shogun's testing framework
  • modular examples should only be exectuted, algorithms tested within c++
  • Test SWIG typemaps, only need to test them since algos tested as above
  • Turn all hand-crafted integration tests into c++ tests (unit or something else), unless we loose test coverage
