Implemented the zooming grid search.

If the zoom level is set to any value other than 0, then the grid width will be divided by
2**zoom_level and centred at the current parameter values. If the new grid is outside of the bounds
of the original grid, the entire grid will be translated so that it lies entirely within the
original.

The rx parameter of the relaxation curve-fitting analysis now has 'rad.s^-1' units defined.

Modified the behaviour of the parameter object units() method.

If the unit is set to the default of None, this method will now return an empty string instead of
None.

Fix for the _prompt.test_diffusion_tensor.Test_diffusion_tensor.test_init_argfail_params unit test.

As the diffusion tensor can now be initialised as None, the None value can be accepted and a
different RelaxError is raised when the params argument is incorrectly supplied.

Updated the minfx version number to 1.0.9 in the release checklist document.

This as of yet unreleased version contains an important fix for parallelised grid searches when the
number of increments is set to one (i.e. a preset parameter).

Bug fix for the lib.arg_check.is_num_tuple() function.

There was a typo in two of the RelaxError objects so that non-existent errors were being raised.

Fix for the _prompt.test_align_tensor.Test_align_tensor.test_init_argfail_params unit test.

As the alignment tensor can now be initialised as None, the None value can be accepted and a

Bug fix for the lib.arg_check.is_num_tuple() function.

There was a typo in two of the RelaxError objects so that non-existent errors were being raised.

Fix for the lib.arg_check.is_num_or_num_tuple().

When the can_be_none flag is set to True, the tuple of None values is now considered valid. This
enable the diffusion_tensor.init user function to accept the spheroid tensor values of (None, None,
None, None), and the ellipsoid tensor values as a tuple of 6 None.

Modified the pipe_control.minimise.grid_setup() function for when no parameters are present.

For the current version of minfx to function correctly (1.0.8), the lower, upper and inc values
should be set to [] rather than None.
