[ITK] optimizer scales and weights

[Matt McCormick]

Hi Luigi,

The SetScales and SetWeights have different purposes.  SetScales is
used to account for different parameters having a different impact on
motion -- for example, translation versus rotation parameters.
SetWeights can be used to keep one parameter constant, etc.  A more
detailed description can be found in the class documentation here:

HTH,
Matt
