Tested validation code on LOFAR and HTRU score generation scripts. Minor changes to improve processing.

Added file listing errors found in the original LOFAR score generation script.
Working framework for the new code. Tested and validated. The new score generation code can deal with multiple parameters - allowing both pfd and phcx files to be processed at the same time. Also provides the option to write candidates to single rather than separate files to save on disk I/O if running as part of a pipeline.
