I think we're going to have to call the quitem ORM "QuoteLine" because to keep consistent with our documents naming schema QuoteItem would be the many to many relationship of linking items to quotes on the documents tab. I don't see any of the objects for those listed like QuoteItem, QuoteContact, QuoteFile, QuoteUrl, QuoteAccount etc.  Also,  in project extension need to add QuoteProject, in Sales Extension add QuoteCustomer, in CRM extension add QuoteIncident, QuoteOpportunity.
