GUIs now import .ui-files directly.

Added PyCharm files!
Commit before Reformatting with PyCharms!

colormap: Added TransparentColormap.
magdata: Added get_magslice method, to_emd and from_emd.
phasemap: Added to_emd and from_emd.
gui: New GUI "PhaseMap Creator".
tests: Moved from ./tests to ./pyramid/tests. Not a package anymore!

forward_model: DistributedForwardModel created which uses the multiprocessing
               package for distributed computations.

Cleanup and documentation!
ramp: New class for polynomial ramps. Instantiated in the ForwardModel.
forwardmodel: Now uses new ramp class.
phasemapper: Ramp functionality moved to ramp class.
reconstruction: Ramp order not used, ramp can be now retrieved from the ramp
                class after reconstruction.
analytic, magcreator: Better and consistent definition of pixel centers and
                      their influence on the phase.
testing: Minor corrections for new syntax.

colormap: New module with colormap subclass which has special functions to
          calculate directional rgb-colors, now used in many plots!
__init__: On star import now also has abbreviations for a few modules.
fwd_model: Now has flags for fitting an offset and/or ramp.
           CAUTION: will be moved next update to new class!
magdata: Removed colorwheel stuff (all moved to 'colormap'). Overhaul of quiver
         plot in 2D and 3D. Now shows mask and uses new colormap for angular
         color coding.
phasemap: Now uses the new colormap for holo plots. Removed color wheel (moved
          to the new class). Added function to add ramps.
phasemapper: Now handles also offsets and ramps in the phase.
             CAUTION: will be moved next update to new class!
projector: Fixed bugs in SimpleProjector. 1) leftmost pixels are no longer moved
           moved to left corner of padded projection (when dim_uv is not None).
           2) odd padding when using dim_uv are now handled properly (one more
           pixel on top and right if necessary).
costfunction: n is now taken from the fwd_model instead of the data_set.
dataset: Introduced the count variable which gives the number of images.
magcreator: In the process of updating, more on next commit.
reconstruction: Also handles ramps and offsets now, properly extracts them after
                reconstruction.
regularisator: New argument 'add_params' is used to cut off input (for offset
               and ramp) which are not used in the regularisation.
scripts: several small changes...
