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.

Reduce Shogun's base class overhead. See here for a hitlist

• Drop Parameter framework
• Drop Model-selection framework and/or move inside Shogun modules
• Drop GP-model selection (quite feasible)
• Drop Grid-search model selection, not necessary, see here
• Drop Serialisation.
• Drop modular integration tests
  • Clean up Shogun's testing framework
    • There are currently two sets of integration tests from python (tester.py and test_one.py).
    • Modular examples should only be executed, 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
      • Add c++ integration testing framework based on googletest

Reduce Shogun's build complexity

• Drop static interfaces
• Make Matlab work from SWIG
• Port all static integration tests to c++
• Build-folder should be the only thing modified by CMake. Get rid of other hacks.
