Not Inherited
All Things in Querki are part of a big inheritance tree. Instances inherit from their Models,
which in turn usually inherit from higher-level Models.
When we say that they "inherit", we mean that the lower-level Things (the Instances) pick up default
values of their Properties from their higher-level ancestors (the Models). So for instance, if the Model
defines a Default View, the Instance will use that Default View unless it redefines it.
This is almost always the right way for things to work, but a very few Properties are different: they
must be defined on each individual Thing they apply to, and should not be inherited. For example, the
Is a Model flag must not be inherited, because if it was, then all the Instances of a Model would
themselves be marked as Models.
So you can use the Not Inherited flag to indicate that this Property should not be inherited from
Models to Things. This is a very advanced Property, and not intended for ordinary use.
