- initial version of fitting atomic positions from a HRTEM image
- works for graphene without defects
- add licence
- correcting peak fitting
- adding real data for testing
- add xyz-output support
- implemented approximate Voronoi diagram to color heptagons and pentagons
- TODO: add to GUI
- implement dual graph for arbitrary tilings
- implement plotting
- introduce inheritance in PointBrowser -> ImageBrowser base class
- add dual graph again to fit_atom_pos
- speed up calculation of dual graph
- start to add Tiling Browser to correct edges in triangulation
- implement neighbors, still wrong
- correct svn keywords
- correct image orientation + extent
- correct neighbors in flip-procedure
- finish work-flow for fit_atom_pos
=> send again to others
- clean up
correct typos
first running version for automatic peak determination 
in energy_dispersion images for Aluminium
- removed energy_disperison (moved to GIT repos)
rename files
add unit cell average

- and GUI for determining reciprocal basis
start analysis of diffraction pattern in polar coordinates

- uses external library pyFAI
figure out units in pyFAI

- testing total image intensity
smooth image edges before FFT to remove artefacts
