//Creates a window where you can change the weight of CV:s for both curves and surfaces
//If you have one CV selected the window will display the weight for that CV.
//if you select more than one CV the window will display the average weight.
//Limitations : You can only set weights for one object at a time.
//Construction history dont work with weights (see realease Notes for maya)
