Molecular dynamics by NMR data analysis

Brought to you by: edauvergne, troelslinnet

Shifted some functions from lib.structure.geometric into their own modules.

The angles_regular() and angles_uniform() functions are now in the lib.structure.angles module, and
the get_proton_names in lib.structure.conversion.
