Copied the grid.py minimisation module from the original multi_processor branch.

The command used was:
svn cp svn+ssh://bugman@.../svn/relax/branches/multi_processor/minimise/grid.py subdivide_grid.py

This module is now part of minfx, but the Grid_info class will be used by the multi-processor code to
subdivide the diffusion tensor grid search. The code needs much work!

Changes to how the model-free and optimisation data/params are passed into the processor instances.

Two data containers are now used, one for the model-free data, the other for the optimisation
parameters. This significantly cleans up the multi-processing model-free interface.

The mpi4py dep check error is now performed by the base relax module.

Shifted the mpi4py dependency check into the dep_check module.

Ported the multi.mpi4py_processor module to the new mpi4py interface.

The sending and receiving of objects is now performed differently.

Added a copyright statement.

Added the dummy post_run() method to prevent the overall time printout in uni-processor mode.

Added some docstrings.

Big bug fix for the model-free grid search!!!

The lower and upper bounds were being scaled iteratively for each spin causing the values to be
ridiculously bigger and bigger. This caused a total failure of the grid search.
