Modified the Grid_info class remove the grid_ops arg.

This is now removed and subdivided into 'inc', 'lower', and 'upper' in the 1.3 line.

The Grid_info class is now being imported.

Eliminated the pre_and_post_amble mess (that can be nicely handled with the verbosity flag).

Conversion from Numeric to numpy.

Many, many whitespace fixes.

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.
