* Updated some of the zoom behaviour * Can now use arrow buttons to move between consecutive diffraction patterns in the single plot
0.0.7
------------------
* Zoom persists in single plots when changing between diffraction patterns or altering the view in some way.
0.0.6
------------------
* Can normalise intensities to counts from provided weights or errors; possible in single, stack, and surface * hkl ticks labelled by phase name, if present, else, phase id: now including surface plot. * (ongoing) Refactoring of plot_cif
0.0.5
------------------
* Better hkl checkbox checking * Doesn't crash if CIF with no diffraction pattern is loaded * Gracefully handles NANs in data when calculating hkl tick offsets * Datablock names replaced with block_id values on single plot title and dropdown data box * hkl ticks labelled by phase name, if present, else, phase id. * Large refactoring of parse_cif
0.0.4
------------------
* Added hkl ticks to stack plot * Enabled hkl ticks to be plotted above the diffraction patterns
0.0.3
------------------
* Separated GUI and plotting code * Fixed crash on changing to surface tab before opening CIF
