Simple Spectral Access use cases

Forgive me for not just lumping these all as "various NOAO spectral
libraries" but I though the different storage formats and associated data
tables would provide for some interesting use cases. Something like a
cutout service might be appropriate for some of the data, the challenging
thing for us however to put all these into an SSA is simply the variety
of local data access methods required.
Cheers,
