Sasview is a data fitting and analysis package for small angle
scattering data. More information can be found at
https://www.sasview.org.
There is some unfortunate cruft to this commit. SasView uses the
xhtml2pdf python package, which has a specific version of html5lib as
a dependency. This module manually loads that version into sasview.
I haven't made xhtml2pdf available as its own package due to these
circumstances.
