/// \brief This class is solely here to coordinate between the various Usd
/// plugin node typeIds and typeNames.  The constructor makes sure that all the
/// appropriate class' StaticData objects get the correct data.
///
/// At some point, the shapes can move to the plugin, but we may want other
/// plugins to be able to identify and reason about things like UsdMayaStageData.
///
/// Normally the data would just be static members of the class.  However, since
/// we want to support our old maya files that still have old node type
/// ids/names, we move the data here so that we can use the same class for two
/// different sets of type ids/names.  If we don't need to support these, we can
/// move the data back as static class members.
///
/// This members of this struct get modified by each class's initialize()
/// function and then a reference is held by each class through the creator().
