10177: Retrieves default quota assigned for storage of user portfolio files,

10179:
10180: Incoming parameters:
10181:
10182: 1. domain
10183: 2. (Optional) institutional status(es). This is a : separated list of

10185: which apply to the user for whom the default is being retrieved.
10186: If the institutional status string in undefined, the domain
10187: default quota will be returned.
10188: 3. quota name - portfolio, author, or course
10189: (if no quota name provided, defaults to portfolio).
10190:
10191: Returns:
10192:

10195: default quota.

10197: If a value has been stored in the domain's configuration db,
10198: it will return that, otherwise it returns 20 (for backwards
10199: compatibility with domains which have not set up a configuration
10200: db file; the original statically defined portfolio quota was 20 MB).
10201:
10202: If the user's status includes multiple types (e.g., staff and student),
10203: the largest default quota which applies to the user determines the
10204: default quota returned.
