Smooth_vortex now can have a homogeneous core with radius larger 1.
Hacky solution for PyQt4/5, change later!

Changed ignore files.

docs: moved up one level.
plottools: added some default label sizes.
version: added to VCS and added a TODO (switch to Git)
fielddata: added rot90 for ScalarData, lot of small changes.

reconstruction: jutil.TakeTime is now used here.
scalebars: Module which allows nice scalebars to be displayed in all plots.
           This is the new default and can be turned off.
ramp: Now stores everything from the dataset directly to self, instead of
      keeping a reference to the DataSet (construct without Dataset in future!).
projector: tqdm now uses tqdm_notebook if used in IPython Notebook!
magcreator: Added functionality for smooth vortices (see de Graef et al.).
kernel: Corrected behaviour of slab geometry (u and v were still switched!).
dataset: phasemappers now accessable as dictionary or list. The append function
         now also takes lists (but projectors and phasemappers can in turn not
         set directly anymore). Se_inv will be updated automatically.
diagnostics: Functionality to access total, directional and magnitude error,
             according to Kemp et al.

kernel: u and v are switched and now finally correct.
        get_elementary_phase is also switched and corrected.
phasemapper: added PhaseMapperCharge from Feng Shan.
forward_model: now uses y instead of phase_vec/Se_inv and now direct properties.
costfunction: corrected some docstrings and documentation comments.
fielddata: corrected some missing integer divisions (// instead of /),
        added plot_streamline().

New API module unclutters the namespace (import pyramid.api as pr).

semper: Implements the SemperFormat class for phasemaps and magnetizations.
forwardmodel: Docstrings for DistributedForwardModel.
phasemap: save_to_text now optionally without header.
ramp: Docstrings added.

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.
