## Normalize a vector : normalize unitV

normalize or unitV takes as argument a vector.
normalize or unitV normalizes this vector for the l2 norm (the square root of the sum of the squares of its coordinates).
Input :
normalize([3,4,5])
Output :
[3/(5*sqrt(2)),4/(5*sqrt(2)),5/(5*sqrt(2))]
Indeed : x=3, y=4, z=5 and 50 = | x|2 + | y|2 + | z|2.
