Refactored so access dates, student counts and auto-enrollment status are additional details which are shown on a second page, and only for a single courseID. Search based on select box choices uses lonnet::auto_instcode_defaults() to construct appropriate regular expressions to pass to courseiddump() from selections made. Breadcrumbs added, now there are multiple pages.
