//-------------------------------------------------------------------------
// Purpose : reorient the facet
//
// Special Notes : This function should only be used if it is acceptable
// to change the underlying data representation of the
// facets (for example the Sierra facet representation
// cannot change and will not permit changing of the
// node orders on a facet)
//
// Also note that if this function is used, the isBackwards
// flag on the facet should be set appropriately.
