+Retrieves default quota assigned for storage of user portfolio files,

 Incoming parameters:
 1. domain
+2. (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.

+   default quota will be returned. 
 
 Returns:
 1. Default disk quota (in Mb) for user portfolios in the domain.
+2. (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
