Title: Improve setup.py.

I had improved the installation script.
This will avoid that synspec and rotin be compiled more than one time. Also
if you are running "python setup.py build" and then "sudo pip install ." this
change makes the synspec compilation to happen only when the module is build.

Related to #16.
