That allocates an array of uninitialized entries and requires you to 
specify them afterwards.  It would be slightly less error-prone to combine 
the two steps.

If you know your arrays A,B,C already, you can just do [A, B, C].

If you don't know them, or are creating them in a loop, you can just do 
`matrices = SparseMatrixCSC[]` to create an empty array and then 
`push!(matrices, A)` one by one.  (You can use the sizehint! function to 
slightly speed this up, but compared to the cost of creating sparse 
matrices I wouldn't worry about it.)
