Adding wrapper for fastsimcoal

I added a wrapper for fastsimcoal to the Bio.PopGen.SimCoal module. This uses the same input format as simcoal, which is in the same module. I also added a file with a test case for this wrapper.

Note: sample.par was changed because I ran dos2unix on it to fix what seemed like whitespace issues during testing. If that is a problem I can revert it back to the old one, but nothing else was changed there.
