consider moving functions into a .py file

[erandichavez]

Consider the functions and classes in your documentation notebook (ham2, my_gausslike, Peak_Position, etc...) into a .py file in your package and then load them in. This will save space and make your documentation notebook more readable.

We did move all of these into the Model.py. Probably we didn't clearly say where we used it in the notebook, we will rewrite the documentation notebook to make it clearer.
