moved progress bar increment code to own function to simplify process of determining increment values for different config scenarios (separate or combined analysis & db update stages, and reset progress bar for db updates or not)
moved get_fileId_id() function to an attribute (ride_id) in attempt to reduce confusion over what is being requested, and to reduce the number of calls to getting the fileId PK
* replaced stats view with stats table - much faster retrieval * new fileId table entry created in archive_data() method instead of buried in Model::XML xml_to_perl() method
* removed begin/commit from delete_record() function, using db cascade delete method * renamed db view stats -> stats_view in preparation for new stats table
