A toggle state that can be read from the registry. This stores a piece of
boolean state information.
When parsing from the registry, this state understands two parameters:
default, which is the default value for this item; and
persisted, which is whether the state should be persisted
between sessions. The default parameter defaults to
false, and the persisted parameter defaults to
true. If only one parameter is passed (i.e., using the class
name followed by a colon), then it is assumed to be the default
parameter.
Clients may instantiate this class, but must not extend.
