//       Class : P3DMainObject
// Description : This corresponds to the "main" object exposed by a
//               particular instance, as returned by
//               P3DInstance::get_panda_script_object().  This object
//               corresponds to the appRunner.main object in Python,
//               and the document.pluginobject.main object in
//               JavaScript.
//
//               This is mostly a wrapper around a P3DPythonObject
//               pointer, and therefore functions like any other
//               P3DPythonObject; but it also handles the special case
//               of being available before Python has been started;
//               and it furthermore reports properties that are
//               generated directly by the core API (like
//               downloadProgress and such).
