NAME
       diag - get diagonal part of a matrix

DESCRIPTION
       This function get the diagonal part of a matrix.

	       csr<Float> a;
	       dia<Float> d = diag(a);

TODO
       Build a csr matrix from a diagonal one or from a vector:

	       dia<Float> d;
	       csr<Float> a = diag(d);
	       vec<Float> u;
	       csr<Float> b = diag(u);

IMPLEMENTATION
       template<class T, class M>
       dia<T,M> diag (const csr<T,M>& a)
