Introduced checks to catch a blank pipelineName field in either the editor or in the pipeline configuration (.yml) file.
Removed redundant "Using BBRegister:" option.
Introduced a more elegant timing reporting system which outputs .csv files, and also fixed and improved the working directory infrastructure for group analysis so that each seed of each derivative has its own directory (needed for parallelization to properly work).
Introduced a separate configurable parameter in the GUI for choosing the number of cores to use for the parallelizing of group-level analysis.
Prepared the file for the changes in the GUI where group-level analysis parallelization has its own parameter for the number of cores to use.
Finished developing group-level analysis parallelization.
Removed older code.
