//
// CLASS DESCRIPTION (polyExporter)
//
// polyExporter is a class used for creating polygonal mesh exporter plugins.
// It is derived from the MPxFileTranslator class and thus implements the
// functions writer(), haveWriteMethod(), haveReadMethod(), and canBeOpened(),
// which are called by Maya when a scene export is executed. This class allows
// the choice of exporting all or only selected poly meshes in the scene.
//
// To use this class, derive a new class and begin by adding the following *.h
// files:
// #include <maya/MFnPlugin.h> - used for defining plugins
// #include <maya/MIOStream.h> - used for input/output operations
// #include <maya/MFStream.h> - used for file input/output operations
//
// The following functions must be implemented:
// creator() - required by Maya to allocate an instance of the derived class
// initializePlugin() - required to register the plugin with Maya
// uninitializePlugin() - required to unregister the plugin with Maya
// defaultExtension() - returns an the export file type extension
// createPolyWriter() - returns a new polyWriter which performs the exporting
//
// For examples, see the classes polyRawExporter and polyX3DExporter
//
