some gimmics for align_to_ef...
fixes and enhancements to wave shifting in paul.toolbox.arpes
specialized alignment code for URu2Si2 added (not fully tested yet)
kz Ef corrections seem to work now
paul.toolbox.arpes: started working on deg2kz (deg->k transformations for wve stacks at different excitation energies)
deg2kz: algorithm working, but still need to iron out some physical issues (related to the meaning of the work function)
deg2kz: moving to map_coordinates for more control over out-of-boundary points (intermediate version, needs some cleaning up and testing)
deg2kz and deg2ky: starting to fix the 'energy-sensitive' bug
deg2ky: energy-dependency fixed now, full 3D interpolation available :-)
deg2ky_single: fixed.
