face alignment .dat file was loading every time for a request, made changes to the import times to make it faster

Made the shape_components sliders work with the multipliers in the backend, able to change the face now

Moved tests and made them work again, added sphinx documentation and added/updated documentation, #4, #5

Moved imm to datasets module, all in preperation of dynamic loading of module, see issues #1, #2, #3
