+ Retrieves default quota assigned for storage of user portfolio files,
+ given an (optional) user's institutional status.
+ Incoming parameters:
+. domain
+. (Optional) institutional status(es).  This is a : separated list of
+    status types (e.g., faculty, staff, student etc.)
+    which apply to the user for whom the default is being retrieved.
+    If the institutional status string in undefined, the domain
+    default quota will be returned.
+ Returns:
+. Default disk quota (in Mb) for user portfolios in the domain.
+. (Optional) institutional type which determined the value of the
+    default quota.
+ If a value has been stored in the domain's configuration db,
+ it will return that, otherwise it returns 20 (for backwards
+ compatibility with domains which have not set up a configuration
+ db file; the original statically defined portfolio quota was 20 Mb).
+ If the user's status includes multiple types (e.g., staff and student),
+ the largest default quota which applies to the user determines the
+ default quota returned.
