"sparsersb" oct-file testing

[Michele Martone]

One year ago or so I've wrote about the inception of "sparsersb"; that
is an oct-file providing a command spawning objects (sparse matrices)
behaving almost like the ones spawned by "sparse" (in terms of
possible operations).

The purpose of this was to give Octave users access to my experimental
sparse matrix library "librsb" --- http://librsb.sourceforge.net/ ,
which is optimized mainly for multithreaded multiplication of large
sparse matrices by a vector. By "large" I mean matrices not fitting in
the cache memory; so to speak, with several millions of nonzeroes. 

While I released the "librsb" library, I haven't done so for 
"sparsersb": it needs some early users testing.

So I invite who uses Octave for sparse matrix-vector multiplication
intensive code to try "sparsersb" and provide feedback, so missing
functionality can be put in a wish list and any bug will be merciless
smashed before a release.
