holoimage: changed colorwheel (now without axes)
magcreator: create_vortex now also allows a 3D-center (2D is extracted)
magdata: new methods: get_mask() and scale_down()
phasemap: changed plotting defaults (new kwargs)
phasemapper: started on electrical contribution

setup.py: Final cleanup
deleted initpyximport, compare_method_errors and get_revision (now in setup.py)

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)

test: changed the dataloader TestCase
pyramex: first experiments with Cython and SCons
dataloader: changed the order in which the dimensions are saved,
        z_len is no longer part of the magnetization (this was the reason why
        we had to divide by res, which is equal to z_len for calculating coeff)
magcreator: shapes are now separate functions, mag_shape is now an argument for
        one unified create_hom_mag-function
phasemap: unification of the phasemap-functions in real space (just the pixel-
        field is calculated different now)

Removed old scripts (AnalyticSolution and DataLoader)
Added several template testcases
