Function for either fixing or allowing parameter values to change during optimisation.
Keyword Arguments
~~~~~~~~~~~~~~~~~
element: Which element to fix.
fixed: A flag specifying if the parameters should be fixed or allowed to change.
Description
~~~~~~~~~~~
The keyword argument 'element' can be any of the following:
'diff' - the diffusion tensor parameters. This will allow all diffusion tensor parameters
to be toggled.
'all_spins' - using this keyword, all parameters from all spins will be toggled.
'all' - all parameter will be toggled. This is equivalent to combining both 'diff' and
'all_spins'.
The flag 'fixed', if set to True, will fix parameters during optimisation whereas a value of
False will allow parameters to vary.
