- examples, test and pycaffe compile without problem (matcaffe not tested)
- tests show some errors (on cpu gradient tests), to be investigated
- random generators need to be double checked
- mkl commented code needs to be removed

Replace MKL with Boost+Eigen3

* commit '70c4320e436f92d0963b2622d20c7435b2f07f30':
  Fix test_data_layer segfault by adding destructor to join pthread
  Fix math funcs, add tests, change Eigen Map to unaligned for lrn_layer
  Fix test stochastic pooling stepsize/threshold to be same as max pooling
  Fixed FlattenLayer Backward_cpu/gpu have no return value
  Fixed uniform distribution upper bound to be inclusive
  Add python scripts to install dependent development libs

Compile errors in boost-eigen branch

previously filled in all NaNs for me, making many tests fail)

make compatible with boost 1.46 and 1.55

1)

fix bernoulli random number generation
