Generate a block diagonal sparse matrix?

[Douglas Bates]

Is there a function in Base to generate a sparse block-diagonal matrix from the diagonal blocks which themselves are stored as SparseMatrixCSC objects?  I thought I should ask before reinventing the wheel.

I added blkdiag() for sparse matrices a few months back (was the first thing I did when I started using Julia). Let me know if it doesn't do what you're looking for.
