WiiAction Controller v0.4.1 (Beta): Fixed mistake of calling the SendData() command even if there was no new data. Roll is the only remaining manipulator function to add. Two issues need to be addressed: Users need a way to halt WiiAction Controller so that they can manipulate the data via the ParaView window; Calling GetData() a second time causes the program to freeze up at the 'Receive' call and leads to a bus error after a few seconds.
