Fix for the final data pipe.

This is created by model selection, so pipe.create() doesn't need to be called.

Added a few additional comments.

Removed a useless check for models of zero length.

The diffusion tensor was incorrectly referenced and the model, parameters, and equation were not
always being set.

Fix for the fix() user function call in the full_analysis.py script.

Fixes for the overfit_deselect() method.

The diffusion tensor object is now correctly referenced and the params variable can be None.

Removed an out of place double quote.

Docstring fix in the base API write_pdb() method for epydoc.

Fix for the OMP model-free optimisation system test.

Switching between pipes was not occurring, so the diffusion tensor appeared to be missing.

Fix for the OMP model-free optimisation system test.

The MF_MODELS variable now exists.
