Modified the system/functional + unit test running code so that only the true unit tests are run.

The current setup was looking for unit tests throughout the relax source tree and accidentally
running the code in the file 'minimise/line_search/test_functions.py'.

Spell check of the 'unit_test_runner' module.

Set the executable bit on the diffusion tensor data structure test module.

Added an initial unit test framework for testing of the diffusion tensor objects.

Changed the diffusion tensor MC sim objects from lists to the ListType 'DiffTensorSimList'.

These changes are part of the solution for bug #7979 (https://gna.org/bugs/?7979).

The 'append()' and '__setattr__()' methods of 'DiffTensorSimList' have been set to dummy functions.

Rearrangement of the diffusion tensor parameter calculation functions.

These changes are part of the solution for bug #7979 (https://gna.org/bugs/?7979).

The 'self._calc_x()' methods of the DiffTensorElement class, where x is a diffusion tensor
parameter, vector, or matrix, have been shifted from the 'data' directory to the diffusion tensor
code of the 'generic_fns' directory. The methods have also been converted into module functions.
The 'self._update_object()' method calls in the 'self.__setattr__()' method have been modified so
that the type of diffusion is passed into the necessary 'calc_x()' functions.
