fielddata: plot_quiver3d figsize renamed to size
        (because it's in pixels, not inch-size of the figure)
plot_quiver3d_to_2d: revamped to be more user friendly,
        directly specify dpi now,
        automatically detecs magnification to get high resolution.
plottools: Added plot_3d_to_2d as a separate function,
        that should be invoked after a mayavi plot.
        Allows fine tuning of 3D plot separate from following 2D plot.

Major changes before Refactoring / Reimagination!file_io/io_vectordata:    ovf-files now can specify the segment that should be read    (if several exist)    vtk-files: fixed an error switching up dim/origin/spacing    major rewrite of _interp_to_regular_grid, now sets up Delauney    triangulation only once (reusable for different magnetisation    components), grid spacing is now mandatory and a conversion factor    is introduced, which can be used to convert units in the vtk file    to nm. Deleted much unused stuff.magcreator/examples:    Added Bloch and Neel type skyrmion support, based on...magcreator/magcreator:    Added create_mag_dist_skyrmion function, which can add Bloch and    Neel type Skyrmions with two different mathematical descriptions    for the domain wall. Fully supports 3D orientation.utils/lorentz:    Added a section to check the phase plate, currently commented out!    Maybe useful in the future or for a full forward model.colors:    Ignored (unavoidable) flake errors (Axes3D "Unused Import")fieldconverter:    Fixed error (wrongly used abs instead of sqrt), now works!    Streamlined convert_A_to_B.fielddata:    field property is now abstract and implemented in subclasses.    angles parameter commented out (delete in the future).    Reenabled axis.set_facecolor(bgcolor) in plot_field (now works!).phasemap:    Made the switch to cmocean.cm.balance colormap (switched colors!)plottools:    Changed figsize default (better fits for newer matplotlib).    New scalebar implementation (black bar now, can have stroke).    Streamlined add_cbar function.    hideaxes now works again (old version used deprecated code)..gitignore:    More general definitions of ignored files.environment.yml:    Updated environmet.

Removed warnings for tight_layout (get rid sooner or later!)
And another environment update (pyFFTW now again accessible via conda!)

dataset: plot_mask now takes kwargs.
fielddata: pad now allows mode changes.
phasemap: fixed bug that did not properly scale vmin and vmax with unit.
io_vectordata: added support for .vtk, .tec files and new interpolation.

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.

fielddata and phasemap: Now use the new plottools module, cleanup of arguments
                        and documentation.
plottools: New module for pretty plotting and different annotations like text,
           colorwheels and colorbars.
colors: Colorbar now has a black circle outline and arrows pointing in cardinal
        directions.
diagnostics: Small documentation fixes and naming 'avg' --> 'avrg'.
docs: Renewed documentation.
