1. Added 2-nd level of parallelization of NN on OpenCL
2. Restructured detector - now all filters work independently:
Variance Filter->Ensemble->NN,  through "buffers"

Added BSD-compatible license to some files

1. TLD now have module structure
2. Made some small code optimizations
3. Fixed Ensemble Classifier according to the original paper - 10
randomized ferns
4. Added comments to most of the functions and methods
