ENH: IO/read_gamic, phase_proc/new solver

1. I have a first version of the gamic_hdf5 reader for testing.
    There will be a filemetadata-file out shortly.
2. Vectorized version of smooth_and_trim
    Just for convenience.
3. Implemented new solver CyLP - speedup of factor 8-10
    Very nice Cython based COIN-OR interface.
4. Implemented multiprocessing for CyLP module 
    Could also be translated for the PyGLPK and CVXOPT implementations.

My 360 rays by 1000 bins problem takes around 360 seconds with the cvxopt implementation.
Using the CyLP module with the coin-or solver it takes around 36 seconds.
The MP approach then takes only 6 seconds.
