0023404: Create SquareConfusion function in Precision package for speed and convenience

Browse Source 
SquareConfusion function was created in FoundationClasses module -> TKMath toolkit -> Precision package.
The function returns square of Precision::Confusion().
SquareConfusion function was corrected in FoundationClasses module -> TKMath toolkit -> Precision package.
Squares of Precision::Confusion() were replaced by Precision::SquareConfusion().
