Detailed Description
Implements a functional corresponding to a (possibly weighted) sum of squares of components of an array::Scalar.
If the vector has component vectors \(x_i\) the functional is
\[ J(x) = c_N \sum_{i} w_i |x_i|^2 \]
where \([w_i]\) is a vector of weights and \(c_N\) is a normalization constant. The value of the normalization constant is set implicitly by a call to normalize().
