Revision 17621 (Modified on 2026-10-18): Large checkin; rewriting how Modlr handle Used-By and error checking The new strategy is to hold a ReadOnly mirror ecospace - and all the error check and used by info is created here. All expressions are parsed into the parts they consists of - and when one such part change is detected the expression is invalidated. This improves severel things: 1. Errors are always up to date (seconds delay in large models) - no need to save to have it refreshed, 2. UsedBy index is always up to date, 3. Better responsiveness in WPF UI editor since no error checking is done in mainthread
