This makes sense indeed

> We were doing some work with the ModelField and noticed that when a field is marked as a primary key it can still have its "NotNull" property set to "false" (the default).  Because we were doing work based on if a field was nullable it was causing a bug on primary keys.  The suggestion is to set NotNull = "true" when a field is marked as a primary key.  This should have no impact to current code as (in most places) a redundant check was being done (see creation of tables where it will add "NOT NULL" based on both isNotNull and isPk -- ideally it should be just based on the former).
> This change makes minor modifications to two files ModelField and ModelEntity.  ModelField.setIsPk() will call setIsNotNull(true) when the primary key indicator is true.  ModelEntity will call field.isNotNull = true when it is reading the primary key elements in the entity definition.
