bbkron Return black-box operator for a Kronecker product.
BB=bbkron(BB1,BB2) creates a black-box operator for the Kronecker
product of operators.
If A1 is the explicit matrix for BB1, and A2 is the explicit matrix for
BB2, the explicit matrix for the Kronecker product is given by
A=kron(A1,A2).
bbkron(BB1,BB2) is equivalent to kron(blackbox(BB1),blackbox(BB2)).
