v2.0.0

Improved iteration procedure

After an initial scaling, the iteration variable is updated using a linear extrapolation off the previous two values and their subsequent errors from the target eigenvalue.

Improved modular structure

Gone is the terrible globalparams file, here is the new, more modular and importable structure.
Each main module (iterator, readinputs, outputs) can now exist on their own and be imported into other python projects.

Documentation

A very rudimentary pdf has been added in docs/pdf that contains documentation on the functions.
This will be expanded and improved in future releases.
