Python wrapper

[edoddridge]

Two enhancements to the python wrapper, namely:

• it no longer deletes the input folder before the start of a run, which means that files placed there by the user can be accessed by the model.
• the 2d and 3d versions of the generator functions have been combined to reduce duplicate code and lower the maintenance burden. This also has the nice side effect of increasing code coverage.
• documentation of the generator functions has been improved.
