Optional-SearchFactor is in degrees --- e.g. 10 = search in 10 degree increments .
Radian-Fraction should be between 0 and 1 --- will search this arc +/- around principal axis.
Optional-bool-UsePrincipalAxes determines whether the rotation is searched around an initial
principal axis alignment. Default = false. Optional-uint-UseLocalSearch determines if a local
optimization is run at each search point for the set number of iterations. Default = 20.
