A C reimplementation of the tricky bits of Python's Popen.

It is currently implemented in a very specific way and might break under general use.

• Support string invocation - Currently only support array invocation
• Support after fork func
• Support all stream modes - Currently everything has to be PIPE

import cpopen
proc = cpopen.CPopen(["echo", "3"])
proc.communicate()
