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

phasemapper: added Kernel helper class with methods to calculate the jacobi
matrix or to multiply a vector with the (transposed) jacobi matrix without
explicitly calculating the full matrix
magcreator: added Shape.ellipsoid
numcore: added (experimental) speed-up for jacobi-matrix (not faster)
scripts: modified get_jacobi to test the new Kernel class,
tests: test_compliance now also searches and creates a list of TODOs

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)

numcore: deleted c1, c2, c3, name changes in phase_mag_real
analytic: name change beta to phi
phasemapper: changes to include numcore
test_compliance: also checkes .pyx files now
setup: now works properly (hopefully on other systems, too)
compare_discs: added script to compare discs
