Notes:

Release Name: nfg_1.0.3

Notes:
This release fixes persistent bugs with the calculation of the tensor used to generate the signal. The calculated tensors were previously not aligned correctly with the plotted orientations.


Changes:
- Changed the 'create_tensor' function in 'mri_sim'. The calculation of the tensor is now determined from more direct (and correct!) equations, which avoid the need for spherical coordinates.
