Added new routines to support new reports. We now report the percent of jobs that contained a skill list (e.g. java sql and python). TODO. remove the "filter"routines. The filter routine were put in to compensate for an issue with our data source. We were getting extra jobs, not related to our search criteries. Those extra jobs were skewing our expected results. Data source now fixed. We can remove the custom "filter" functions in this listing. Related: new filters.clj listing contains new custom filter logic for new reports.
