Log Message:
Changes to allow component classes to be part of a component hierarchy.
The problem was that if a class defines 'getParentComponent()' for its
instances, there was no way for it to define 'getParentComponent()' for
itself!  Now all such API's are called on an object's '__class__', passing
in the instance.  This means that if a class is used as a component, its
metaclass 'getParentComponent()' will be called on it, producing the right
result in context.  Similar changes were made for other IBindingSPI methods
such as '_getConfigData()' and 'getComponentName()'.  These changes are
needed to support peak.model class families that need their features to
refer to other classes in the class family -- the element classes need to
be used as context components for the features.
