+		The starting point of this script was Anthony D'Agostino's raw triangle format export.

+
+		Usage:<br>
+			Select the mesh to be exported and run this script from "File->Export" menu.
+			The toggle button 'export 3 files' enables the generation of 4 files: one global
+			and three with the three different views of the object.
