Orthogonalise a basis using modified Gram-Schmidt (and normalise)
Transform basis {vk} to orthonormal basis {ek} with k in range 1..N for j = 1 to N ej = vj for k = 1 to j-1 ej = ej - <ej,ek>ek //NB Classical GS has vj in inner product end ej = ej/|ej| end
Modifications Mar. 2011 - Patrick Sauer - added variant that returns normalisation multipliers
