Iftach Sadeh / ctools

# Conflicts:
#	src/Makefile.am

Added a python wrapper file for ctphase.
Added tests of the python wrapper for ctphase (and made sure they pass).
Added unit information to the '.par' file.

Note that test_python_ctools.py could ultimately replace all ctools, as for the shell script we anyways to not recover the results. Still, the shell script may still make some limited sense.
