testPerpendicularUnitRowsAndColumns Method

Test if all rows and columns are unit length and are perpendicular to each other, i.e., the matrix is either a pure rotation (determinant is +1) or is a mirror (determinant is -1).

• Note: such a matrix is called orthogonal and its inverse is its transpose.
