//
//  Procedure Name:
//      polyUVCutCtxAction
//
//  Description:

//  Input Arguments:
//      $actionType - 1. Cut highlighted or selected edges
//                    2. Sew highlighted or selected edges
//                    3. Unfold and pack UV shell in current UV tile
//                    4. Unfold and pack UV shell in an empty, neighboring UV tile
//
//  Return Value:
