plottools.plot_3d_to_2d function should be used now for more control!

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.

rgb_from_vector fixed to properly generate luminance.
get_avrg_kern_field now properly handles fits without ramp.
plot_avrg_kern_field now also returns the plotting axis.
plot_quiver ar_dens behaviour changed:
    now has 'auto' functionality and also bins instead of showing
    every nth arrow. Arrow color is now white with black stroke.

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.

quiver_field now allows interpolation.

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.

forwardmodel: DistributedForwardModel should now properly close pipes.

forwardmodel: DistributedForwardModel now has __del__ method
(not working as it should, processes still live on...)

environment.yml: upgraded to scipy=1.0

fielddata: fixed tests!

projector: RotTiltProjector now ends in the correct coord system!
diagnostics: Refined the LCurve class (now saves stuff!)
lorentz: Added preliminary Lorentz imaging functions!

costfunction: chisq_m/a now track their results (better way?)
diagnostics: added LCurve class (not finished), comments for SVD
fielddata: properly ordered properties, added plot_field for ScalarField
phasemap: fixed bug for symmetric=False, cmap=None (no proper default!)

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.

Started working on reader for binary ovf files (WIP).
utils.pm now works with PhaseMapperFDFC.

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.

diagnostics: now takes magdata as input instead of a vector.
             Plotting routines for diagnostics added.
fielddata: Added quiverkey if b_0 is provided.
phasemap: If appropriate unit is provided, will be labeled as "Gain Map".
scalebar: Cleaned up and clipping added.

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.

phasemap: Now supports flips, rotations and shifts with ndimage.
          Added plot_phase_with_hist to plot histograms (for difference plots).
fielddata: FieldData now properly plots contours and masks (new).
dataset: set_3d_mask now uses the new mask capability of FieldData.
         Default is no longer "logical backprojection".
io_phasemap: Now includes .tif (although that does not always work).
setup.py: Deleted deprecated depencencies.
Renamed a few plot commands to plot_...
Rollback to RdBu as colormap (back from Spectral).

fielddata: slices now include z-component which will be plotted in plot_field.
colors: Minor tweaks. Mainly for Rec. 601/709 input.
phasemap: Now uses 'Spectral' as a colormap.

Now uses an improved cubehelix colorwheel for most purposes.
Other variants are also provided.
Removed hue_mode.

fielddata: Added plot_quiver_field convenience function.
io_phasemap: Added functionality for images separately from HyperSpy.
phasemap: Automatically normalise confidence.
projector: Quaternion for tilt around x-axis corrected (was falsely around y).
reconstruction: Added verbose option (True by default).
reconstruction_2d_from_phasemap: Plotting optimised.

Renaming of variables in PhaseMapperRDFC.jac_T_dot to make more sense...

phasemapper: PhasemapperRDFC: Now the adjoint is calculated correctly (switched
        slicing order, took conjugate of kernel FFTs, deleted superfluous minus
        sign). Results are the same, but calculation is now CORRECT!
fft: Correction of numpy rfftn_adj.
fielddata: Added option for uniform color specification.

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().
