Elena Lukashova 647ed85345 Adapting PHY code to work with mex-functions:
1. Moving get_pmi into a separate file and making corresponding
changes in CMakeLists.txt.
2. Creating PHY_MEX library with functions required for the receiver
mex-functions.
3. Making necessary changes in defs_UE.h so that mex-functions
do not complain about multiple LOG_ calls.
