+Incoming parameters:
+1. user's username

+
+Returns:
+1. Disk quota (in Mb) assigned to student.
+2. (Optional) Type of setting: custom or default
+   (individually assigned or default for user's 
+   institutional status).
+3. (Optional) - User's institutional status (e.g., faculty, staff
+   or student - types as defined in localenroll::inst_usertypes 
+   for user's domain, which determines default quota for user.
+4. (Optional) - Default quota which would apply to the user.
+
+If a value has been stored in the user's environment, 
+it will return that, otherwise it returns the maximal default
+defined for the user's instituional status(es) in the domain.

+=item * &default_quota()
+
+Retrieves default quota assigned for storage of user portfolio files,
+given an (optional) user's institutional status.
+
+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.
+   If the institutional status string in undefined, the domain
+   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
