create import system for open source spectra sources

[jywarren]

like the HITRAN and ASTER datasets.

this should also tag the imports as "ASTER" "HITRAN" and/or "transmission" "mid-infrared" "imported" etc etc

and will be the basis of identifications

• http://archive.publiclaboratory.org/hitran-spectral-library/
• http://archive.publiclaboratory.org/aster-spectral-library/

Huge list here: http://www.lohninger.com/spectroscopy/dball.html

Queries the NIST ASD lines1.pl webform using wget and parses the returned output using sed and matlab intrinsics. Looks ugly, and probably could be optimized, but works OK for the meantime.

the relevant url is:

(for He)

and grab whats between the PRE tags
