HTML::Mason::Component::Subcomponent - Mason Subcomponent Class
This is a subclass of HTML::Mason::Component.
Mason uses it to implement both subcomponents (defined by <%def>) and methods (defined by <%method>).
A subcomponent gets most of its properties from its owner.
Returns 1 if this is a method (declared by <%method>),
0 if it is a subcomponent (defined by c<< <%def> >>).
Return the component object that this subcomponent or method was defined within.
