GUIs now import .ui-files directly.

Refactoring: Replaced MagData with VectorData and added ScalarData class (and common superclass FieldData).
magnitude is now called field (which is more appropriate)
projector now uses FieldData to process both vector and scalar data (foundation was in place before)

fieldconverter: methods to convert M to A to B
magdata: a bit more parameters for quiver_plot3d(), added contour_plot3d()
phasemapper: pm() extended for different projections (not just simple)
kernel: u and v switched (now named after the unit magnetization direction, which makes much more sense)

Added PyCharm files!
Commit before Reformatting with PyCharms!

Added .idea folder with PyCharms settings.
Changed icon.ico (now round).
PhaseMap and MagData: Now use h5py to load/save data (via HyperSpy).
Deprecated loading routines (x3d) are gone now!
tests: All tests now reflect this change.
scripts: Streamlined some scripts. Many are now in separate project:
Script-Vault

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!

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.

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...

costfunction: Now takes a ForwardModel as input instead of DataSet.
forwardmodel: New private function for processing one image (multiprocessing).
magdata: Quiver Plots (2D/3D) now support color encoding (angle or amplitude).
         Private method for creating the appropriate colormap.
reconstruction: Now takes Costfunction as argument instead of DataSet.
regularisator: Introduced ComboRegularisator.
scripts: New scripts.

Phase maps now also have a mask and a confidence matrix.
Began new script structure (temporary folders created).
Cleanup, logging and documentation done.
config: NTHREADS is now set here.
dataset: Method for creating 3D masks added.
phasemap: Mask and confidence matrix added. Padding and cropping supported.

tests: Changed accordingly.

projector: RotTiltProjector implemented!
quaternion: New module providing quaternions!

magdata: added convenience functions for flipping and rotating of magnetic
         distributions, fixed bug with ar_dens.
phasemap: now also has a mask which will be used to construct a 3D-mask for the
          magnetic distribution during reconstruction. Added setter/getter.
          Added copy(), scale_down()/scale_up() convenience functions.
          !CAUTION! Only NetCDF4 files save every new parameter!
projector: Fixed hidden bug in X/YTiltProjector, which was problematic during
           tilts over 360°. Now uses linear algebra (much clearer!).
           get_info() function now can be used non-verbose (for filenames).
dataset: added several setter/getter, addes set_3d_mask() for simple 2D tasks,
         renamed mask to confidence (for Se_inv construction)
tests: updated to include the fixes and new functions introduced in this update!

magdata/phasemap: load and save methods now dynamically save with absolute and
        relative paths. Relative paths are defined in the config.py file!

tests: implemented the missing TestCases!
dataset: mask is now created if not given!
phasemapper: guaranteed np.float32 format for RDRC (expected by Cython)
projector: now uses fft.FLOAT

docstrings: updated!

scripts: minor modifications
scripts - reconstruct_random_pixels: now use optimize_linear
testcases: analytic, compliance, kernel, magcreator, magdata, projector

kernel, phasemapper: now use the new pyramid.fft module.
MagData, PhaseMap: now use np.float32 instead of np.float64
MagData: new quiver_plot3d with just matplotlib (buggy and still WOP).
logging: deleted several logging.debug prompts for speed up.
util: deleted module!

Se_inv: is now handled differently, defaults to eye-matrix, but can be set
        later (added a few convenience functions to DataSet)
utility: (re-)added utility module for index conversion
kernel/phasemapper: can now use FFTW library and operate on pre-allocated
        arrays
dtype: set dtype of arrays to np.float32/np.complex64 (halves memory size),
       also applied to numcore routines!
magdata: quiver_plot can now plot every n-th arrow (yet untested!)
reconstruction scripts: modified several reconstruction scripts.

setup: Changes to setup.py, pyramid.version to fit to numpy and jutil
       now uses __all__ magic and supports from pyramid import *
tests: changes to test_compliance/magcreator/analytic (should now work)
collaborations: added several scripts for Patrick
reconstruction: added batch file for the reconstruction of several configs
test methods: (unfinished) scripts for fftw tests and kernel comparisons
paper 1: ch5-4 changed padding values to 0, 1, 3 and 7
plotting: deleted plt.show() lines (have to be done manually now or via Spyder)
logging: now named _log instead of LOG (private variable instead of constant)
         also some logs were disabled, because Pylint says they are slow...
reconstruction: now has info argument (pass a list in which cost info is copied)
phasemapper: changed sign of constant PHI_0, is now correctly positive (instead
             the negative z-integration is taken into account which was not done
             before!)
kernel: now uses FFTW, numpy code was changed accordingly and is still available
phasemapper: also uses FFTW now, work in progress: FFTW for jac_T_dot

Added a steppest descent minimizer for lp problems and added an experimental split-bregman optimizer.

        m: i'm'age
        n: i'n'put

fixed some minor compilation bugs and updated to current jutil. prepared jutil reconstruction routines.

Still to do: PhaseMapperElectric does not work
             3D reconstruction does not converge

minor changes to plotting methods (PhaseMap now plottable without colorbar).
phase_map: gain can now be set to 'auto' (5 fringes, determined by max. phase).
renamed 'density' to 'gain' (makes more sense).
regularisator: started to include norms and more kinds of regularisations.
mag_slicer: GUI which can go through loaded magnetizations along the major axes.
paper 1: minor changes to the scripts for the results.

Many Doctring corrections, all plots now have a "show" parameter to not show a
plot at the end of the method (needed for guis and such).
magdata: quiver_plot: axis switch for x-projection, implemented logarithmic
         arrows and scaling feature.
projector: added to_mag_data() method to directly produce a projected
           magnetization distribution.
