I might be interested in this, but the application I'm thinking of would
require primarily that it is *fast*, especially for large data sets where
attention to the cache heirachy is important.  ie., it would need to use
BLAS as a back-end, while (implicitly) reordering indices in memory as
appropriate (perhaps the FLAME library would be useful here?
http://www.cs.utexas.edu/users/flame/).  This might be a bit beyond what is
realistically possible for a generic tensor library, but I thought I'd ask.
