provide unit-level course/resource RSS feed

[pkleymee]

Right now the RSS feeds for a top-level unit or a sub-unit that contains other sub-units don't provide the course/resource information. They only provide the first layer of nested sub-units. For example:

http://open.umich.edu/education/med/feed - this provides the M1, M2, Health OER Network and Resources sub-units in the RSS feed. What it should provide are the courses/resources within each of those sub-units. For the actual page: http://open.umich.edu/education/med

http://open.umich.edu/education/med/oernetwork/feed - this has multiple levels of sub-units that contain courses/resources but they are not provided in the RSS feed. Only the first level of sub-units is shown. For the actual page: http://open.umich.edu/education/med/oernetwork
