cmocean, hyperspy to yml file.

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

phasemapper: Now without fft.shift (not necessary thanks to fft.fftfreq)
magcreator: Now vortices with orientation along negative axes possible.
fielddata: HDF5 load updated to new HyperSpy BaseSignal (all signal axes now...)

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)

Added PyCharm files!
Commit before Reformatting with PyCharms!

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!
