Unorthodox params.py

[jcohenadad]

The README asks to edit the file params.py and then run the code, which fetches the modified file. This is a bit unorthodox, because modifying the source code will create out-of-sync versions from the git repository, which could cause errors/confusions.

A better approach would be to ask the user to copy params.py into another file that would not be under git, edit it and then run the code.

To facilitate the transition with minimum code surgery, we could rename the current params.py into params_template.py, and ask user to create a file params.py
