Abstracted uuid creation logic from base classes
Improved the layout of controls in the export panel
Added option for indenting the JSON output (space saver)
Animation option is now an enum that requires a user to select between POSE and REST
Abstracted animation logic into a new module reducing the size of mesh.py
Improved indexing speeds for vertex colours and normal vectors
Node uuid is now based on name and will be persistent ver multiple exports
Empty arrays will no longer assign None to key values
Copying files will no longer remove the destination, additionally destinations are tested to see if the same as the source

just a Typo correction Line:43

Changed from incorrectly iterating over the keys to over the actual intersection points in the array.
