documentation: minor changes and updates of docstrings

regrid: Added many scripts for regridding by Jörn
logging: Introduced logging
scripts: Added Scripts for regridding and simulating stuff for cooperations
removed: Unused test scripts
structure: Many new restructuring aspects already implemented

modularity and compatibility with future algorithms and ideas.

(At the moment a bit slow, optimization with Cython seems necessary).

Replaced res with a for the grid spacing
(resolution is a reserved word in electron microscopy
Work in progress: jacobi matrix for projection

pyramid: all docstrings in numpydoc (package installed) format (used by spinx)
holoimage: removed error, phase was falsely multiplied by pi/2
magcreator: removed create_mag_dist_comb, renamed functions for disc and vortex
magdata: Allows creation of empty MagData objects and easy adding of magnitudes
phasemap: Allows units to be set for plots, added 3D plot
phasemapper: Electrostatic component implemented
projector: Projection now includes thickness profile
docs: support for html, latex and pdf (experimental), use "make *" in shell
scripts: new structure, deleted some compare_* functions, added test_methods
.hpignore: now also ignores *.c and _* files (_build used in docs)

magcreator: Added the second angle for the magnetization
reconstructor: Changed method name
all others: Changed "beta" to "phi" to reflect the new angle in magcreator

Scripts are nearly adapted to the new structure and easier to read.
(Except analytic module and scripts get_jacobi and inverse)
