+with checkboxes to allow a course to be categorized,called recursively.
+
+Inputs:
+
+itemcount - track row number for alternating colors
+
+cats - reference to array of arrays/hashes which encapsulates hierarchy of
+      categories and subcategories.
+
+depth - current depth in hierarchy of categories and sub-categories - 0 indexed.
+
+parent - parent of current category item
+
+path - Array containing all categories back up through the hierarchy from the
+       current category to the top level.
+
+currcategories - reference to array of current categories assigned to the course
+
+Returns: $output (markup to be displayed).
