Teuchos::RCP<Epetra_CrsGraph> Stokhos::sparse3Tensor2CrsGraph	(	const Stokhos::Sparse3Tensor< ordinal_type, value_type > &	Cijk,
		const Epetra_BlockMap &	map
	)

Build an Epetra_CrsGraph from a sparse 3 tensor.

Builds a sparse graph from a sparse 3 tensor by summing over the third index. This graph then represents the sparsity pattern of the stochastic part of the block stochastic Galerkin operator. Redistributing the graph should then provide a suitable parallel distribution for block stochastic Galerkin linear solves.
