// --------------------------------------------------------------------------
// The following class wrapper is due to a limitation in Qt Script Engine.  It
// requires all methods that return pointers to user classes that are derived from
// QObject actually return QObject* (not the user class *).  If the user class pointer
// is returned, the script engine treats it as a QVariant and doesn't create a
// javascript prototype wrapper for it.
//
// This class allows us to keep the rich return types in the main API class while
// offering the script engine a class it can work with.
//
// Only API Classes that return custom classes needs to implement these wrappers.
//
// We should continue to look for a cleaning solution to this problem.
