7314: Incoming parameters:
7315: 1. domain
1.536 raeburn 7316: 2. (Optional) institutional status(es). This is a : separated list of
7317: status types (e.g., faculty, staff, student etc.)

7319: If the institutional status string in undefined, the domain
7320: default quota will be returned.
1.472 raeburn 7321:
7322: Returns:
7323: 1. Default disk quota (in Mb) for user portfolios in the domain.
1.536 raeburn 7324: 2. (Optional) institutional type which determined the value of the
7325: default quota.
1.472 raeburn 7326:
7327: If a value has been stored in the domain's configuration db,
7328: it will return that, otherwise it returns 20 (for backwards
7329: compatibility with domains which have not set up a configuration
7330: db file; the original statically defined portfolio quota was 20 Mb).
7331:
1.536 raeburn 7332: If the user's status includes multiple types (e.g., staff and student),
7333: the largest default quota which applies to the user determines the
7334: default quota returned.
