The class searches for a CUDA installation directory and provides accessors for relevant bits of info about it.

Added new option --cuda-path=<path> which allows overriding default search paths. If it's not specified we look for CUDA installation in
/usr/include/cuda and /usr/include/cuda-7.0

Once CUDA installation is found we look for libdevice bitcode files and associate them with appropriate GPU type.
