Re: ch-ch-update: series, closed-form series, and strides

One thing that I've found from various c++ vector/matrix libs, is that the 
most useful have flexible storage backends.  In other words, all of them can 
allocate their own storage that they 'own', but the most useful can also 
wrap a matrix 'view' around existing storage.  This allows interworking with 
other libraries.
