A few more formatting changes.

A few fixes to the formatting.

Finished changing the index naming.

The indecies 'data.xx_index' and 'data.xx_local_index' have been replaced with 'data.xx_i' and
'data.xx_li' respectively.

Change of Psi to O, formatting, and shortening of indecies.

Changed all references of the orientational diffusion parameters from Psi to O.

Shortened the equations in the docstrings of 'maths_fns/jw_mf.py'.

Formatted the assignment of functions in the method 'setup_equations' to improve visibility.

The indecies 'data.xx_index' and 'data.xx_local_index' have been replaced with 'data.xx_i' and
'data.xx_li' respectively.

Formatting changes to the formulae in the docstrings of the functions in 'maths_fns/jw_mf.py'.

Finished cleaning up of the code in 'maths_fns/jw_mf_comps.py'.

Bug fix.

In the function 'calc_diff_S2f_S2s_ts_djw_comps', the factor 'data.fact_te_djw_dti' which is not
used was being calculated rather than 'data.fact_ts_djw_dti'.

Clean up of the code in 'maths_fns/jw_mf_comps.py'.

relax release 1.0.2.

This release corresponds to many changes to the Brownian rotational diffusion tensor.

It includes the shift to the geometric parameters

Diso = 1/3 (Dx + Dy + Dz),
Da = Dz - 1/2(Dx + Dy),
Dr = Dy - Dx / 2Da.

Numerous bugs in the old correlation time, weights, and direction cosine code have been fixed. A
few of these bugs had been fixed previously but those fixes were somehow lost. Two major problems
in the calculation of the Hessian of the ellipsoid direction cosines have been fixed and the
ellipsoid diffusion tensor now minimises orders of magnitude faster.

Renamed the direction cosine function from 'geometry.py' to 'direction_cosine.py'.
