// DESCRIPTION:
// 
// Produces the command "flipUV".
//
// This is a simple plug-in for demonstrating the "MPxPolyTweakUVCommand" class to manipulate UVs.
// The syntax of the command is:
//
//  flipUV [-es on|off] [-fg on|off] [-h on|off]
//
// Flags:
//
//  -es -extendToShell on|off 
//  -fg -flipGlobal on|off 
//  -h -horizontal on|off
// 
// To use this plug-in:
//
//  (1) Select UVs from a mesh.
//  (2) Invoke the "flipUV" command. 
// 
// Depending on the type of texture used, results might not show up in the modelling windows.
// To see the result, use the UV Editor.
