Compute norm of a vector, or of a set of vectors.

   N = vectorNorm(V);
   Returns the euclidean norm of vector V.

   N = vectorNorm(V, N);
   Specifies the norm to use. N can be any value greater than 0. 
   N=1 -> city lock norm
   N=2 -> euclidean norm
   N=inf -> compute max coord.

   When V is a MxN array, compute norm for each vector of the array.
   Vector are given as rows. Result is then a [M*1] array.

   Example
   n1 = vectorNorm([3 4])
   n1 =
       5

   n2 = vectorNorm([1, 10], inf)
   n2 =
       10
