Pygmi

----------------------
* Removed libraries not needed etc
* Fixed a problem with adding a gravity regional dataset to calculated gravity.
* Updates to the speed of the calculation for magnetic data.

--------------------
* Update to setup for hosting on pypi
* Added the possibility for ENVI files to have .dat extension
* Allowed uint files to have a no data value of 0 where none is defined
* Fixed bug with Surfer export
* Fixed bug with regional test
* Equation editor bug fix
* Fixed a bug where profiles were not saving to images correctly

---------------------
* Progress Bar on Main Interface. New progress bars include time left.
* Reprojecting bug fix for datasets with negative values.
* Fixes to tilt depth and new progress bars
* Added Column to tilt depth to specify contour id. Also removed redundant
progress bars. Sped up smoothing with median.
* Added tilt depth algorithm.
* Bug Fix with tilt angle.
* Added RTP.
* Cluster and Fuzzy analysis had a bug when connecting external data
* Changed where rows and columns displays on modelling software, for people
with lower resolution screens. Made small improvement to drawing speed on
profile view.
* Added references to the help.
* Modelling now has variable size cursor.
* Change to modelling cursor.
* Updates the behaviour of the slider on the profile view of the 3D
modelling module.
* Grids on kmz export were upside down
* Mag and Grav calculation buttons simplified.
* Gravity regional addition (scalar add) in modelling program now modify
calculated data, instead of observed data - so that original data is
honoured.
* Update to kmz export. The export now can allow smooth models. Update
also allows new projection format for igrf, data reprojection and kmz
files.
* Projections improved and expanded.
* GeoTIFF now save tfw world file. Contour GeoTIFFs are now 3 times
bigger, to improve resolution. Contour lines now have double thickness.
* Sunshaded GeoTIFF is now the same as the on screen version.
* Add save model to 3D modelling module.
* Primary Help completed.
* First version with a helpdoc button on main interface.
* Fixed a bug on the Geosoft import.

------------------------
* Fixed a display bug in modeller where data was not visible.
* Added Geosoft grid import
* Added Geopak grid import
* Fixed a python 2.7 print function bug

------------------------
* Increased size of font for ternary colorbar.
* Corrected issues with modelling information display, especially w.r.t. remanence.

------------------------
* Added ternary colorbar
* Fixed ability to save 3D images on new smoothing
* Bug fix - masking problem with ER Mapper import
* Added extra 3D display functionality
* Added smooth model
* Added marching cubes
* Forced full field recalculation to avoid bug
* Fixed layer import bug
* Bug Fix in model import
* Fixed bug when resizing some models
* Fix for bad values in reprojections.
* New display of point data.
* Equation editor improved to use numexpr.
* Fixed a bug regarding duplicate data names in interpretation module.
* Added a few reports in 3D modelling module.
* Improved the multi-band select by making it a context menu.
* Update help reference.
* Update to python 3.4.2 - includes a dependency on numba. No longer use cython
* Added some seismology routines.
* Fixed writing of null value to file when exporting ENVI format.
* Query for which datasets to connect added.
* Added new gridding technique. and fixed bugs related to vector imports.
* Add a custom data range to the profile view on the modelling module.
