If no value is stored in the current ExtensionContext
for the supplied key, ancestors of the context will be queried
for a value with the same key in the Namespace used
to create this store.
For greater type safety, consider using ExtensionContext.Store.get(Object, Class)
instead.

to create this store. If no value is found for the supplied key,
a new value will be computed by the defaultCreator (given
the key as input), stored, and returned.
