// Abstract: Header for SVDFit routine.  This wraps up the lower level SVD 
//           stuff from Ronen Barzel.  This is the leve of abstraction used
//           by the outside system.

// 21May1996 ChuckR    Initial code start
// 13Apr1999 ChuckR    Templatize and conform to Kineform project style
// 25Jul1999 ppsloan   SVDMat/Apply added - for saving the SVD of a matrix
