+
+Retrieves usernames:domains for users in the specified course
+with specific role(s), and access status. 
+
+Incoming parameters:
+1. course domain
+2. course number
+3. access status: users must have - either active, 
+previous, future, or all.
+4. reference to array of permissible roles
+5. reference to array of section restrictions (optional)
+6. reference to results object (hash of hashes).
+7. reference to optional userdata hash
+Keys of top level hash are roles.
+Keys of inner hashes are username:domain, with 
+values set to access type.
+Optional userdata hash returns an array with arguments in the 
+same order as loncoursedata::get_classlist() for student data.
+
+Entries for end, start, section and status are blank because
+of the possibility of multiple values for non-student roles.
