Repository cleanup

[mz2]

Separate into...

• [x] MPGestures: this now created fork of DollarP_ObjC with a more idiomatic API with stroke sequences as a top level object (original has not been maintained for a year, and the algorithm is small -- I see no point in maintaining API compatible).
• [x] ALGLIB.framework: a version of ALGLIB as an OSX framework / iOS static library.
• [x] MPLearningMachines: machine learning algorithms, for now the random forest classifier from ALGLIB.framework used for the supervised layer of pattern detection, but might also gain dependency to LDA, LSM, etc classification capable models.

[mz2]

This has been completed, separate framework targets introduced and code divided across two repositories (gestures / general learning).
