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.

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

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)

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.

docstrings: updated!
costfunction: CFAdapterScipyCG obsolete, deleted estimate_lambda()
dataset: use_fftw and threads obsolete
diagnostics: implemented stuff... much stuff...
fft: Docstrings and implementation of threads
magcreator: fixed bug in slab (dimension mix-up)
phasemap: plot now also returns colorbar
reconstruction: PrintIterator and optimize_simple_leastsq obsolete
regularisator: Docstrings
scripts: minor modifications
scripts - reconstruct_random_pixels: now use optimize_linear
testcases: analytic, compliance, kernel, magcreator, magdata, projector

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.

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

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.
gui/create_logo: removed (obsolete and unuseful).
gui/mag_slicer: added!

regularisator: new module to represent different regularisation strategies
costfunction: changed to use the new Regularisator classes, changed arguments!
dataset: fixed bug that always displayed the own phase maps instead of provided
reconstruction: changed to use the new Regularisator classes, changed arguments!
scripts/rueffner_file: tried to avoid Memory Error (no success)
scripts/zi_an: added holographic contour plots with overlayd magnetization
scripts/reconstruction_sparse_cg_test: now uses Regularisator classes and plots
                                       phase differences (original - reconstr.)

projector: ALL projectors can now handle arbitrary dimensions
dataset: reverted to old strategy (dimensions must match)
reconstruction: least square method now also with regularization of order 1
scripts: cleanup and streamlining, added projector_test

dataset: phase map dimensions do not have to match anylonger
        (just with the connected projector)
reconstruction: simple least square: added regularisation of 1. order
scripts: stuff which will be cleaned up in next commit

magdata: implemented save_to_x3d (Bielefeld collaboration)
template.x3d: template for the x3d output (header file with spin-blueprints)
numcore.kernel_core: implemented multiply_jacobi_T_core
scripts: added vtk scripts for full nanowires and segments
         script to process file by Daniel Rüffner

pep8: optimizations
phasemapper_core: numcore module for phasemapper
scripts: compatibility with new structure
reconstruction: new scripts

package: some minor corrections (mainly import statements), some old functions
         were revived (e.g. in MagData)

scripts: adaption to the new structure and sorting (more work is to do here...)

_version: __version__ string is now imported from this file

phasemapper_core.pyx: added to separate the corresponding numcore_functions
                      from kernel_core.pyx

Renames:
datacollection --> dataset
optimizer      --> reconstruction

scripts:
interactive_setup is now implemented in an extended Spyder startup file.
some other scripts are now
the rest is NOT adapted, yet, which is the next task at hand
furthermore scripts will be sorted and unused ones deleted in the next commit
