Master updated 12/02/2020 - Tom McAuliffe
Change include:
New phase data structures: phase files, cifnames and masterpatterns (.bin files) specified. Phase_Builder_RTM function updated accordingly to handle these.
Integration of the RTM and PCA modules.
- RTM example deck for indexing of a full map with a single candidate phase.
- PCA example decks for clustering of combined EBSD/EDS datasets, and EBSD-based phase ID and indexing.
- PCA postanalysis decks for chemical analysis (as function of phase) and RC-EBSP comparison to template simulations.
- Available with (adjustable) spatial weighting kernel.
Gitignores for phase files / folders fixed
