Remove PyNE relevant code from your script and include in pyne fork

[makeclean]

We need to put the PyNE relevant code into your fork of PyNE. You can then import the appropriate function back into your script. If you can talk to @biondo to see how this would be done.

• Determine the parts of your script that are relevant to include in the PyNE mcnp class
• Incorporate changes into PyNE
• request your changes are integrated into PyNE
