Introduced an error check which prevents the user from saving a
pipeline_config.yml file with a blank "Pipeline Name" field, and also
warns the user when they load a pipeline config file with a blank
pipeline name field instead of just flat out crashing.
Introduced a warning for the user when a pipeline config file with a
blank pipelineName field is loaded (if the user removed it via text
editor), instead of crashing.
Added a check which prevents a crash from happening when the user tries
to load or edit a pipeline config with a pipeline name that is an
integer.
Added more thorough in-code documentation.
Improved documentation.
Made code changes to enable/fix parallelization in group analysis.
Added GUI option to specify how many cores to use in running group
analysis in parallel.
Introduced the option to turn off z-score standardizing for derivatives,
or have it on/off (apply warp to template and smooth on both z-scored
and non-z-scored derivatives).
Finalized changes for the ability to toggle z-score standardizing
derivatives.
