Updated the uWeb model to only update changed fields when performing a save. Additionally, the primary key value of a field can be changed and saved. This is achieved by storing a copy of the record information in a _record attribute, from which differences are generated on Saving. This *does* make the old method of Record creation invalid (creating a new record and writing fields to it), and this will need to be fixed.
