Add first pass at incorporating the full data export report into the codebase.  This first pass does not use the Excel Template that had been created, but simply exports to Excel using the default XlsTemplateRenderer.  The benefit of this is that we can more easily only export those datasets of interest.  The downside is that there is less descriptive text or built-in formulas that might be useful.  For now, this runs the report synchronously in the browser, and the user must wait for it to complete.
