Added the option to specify a relaxation factor for cross-validation to
the GUI (functionality was already present). Default is 1. Using one
will run a normal crossValidation. WriteprintsAnalyzer currently does
not have an implementation of crossVal with relaxation factor, so it
does not work and informs the user if they try to run it with one.
Updated the WriteprintsAnalyzer description string for the class editor
Cleaned up some some chunks of code
started to add props file
Added properties file to JStlyo. At the moment it only keeps track of
number of calc threads, but I'll expand it to other preferences
eventually. Default file will be generated if one is not present at
runtime.
