Generalize hovers to show information from more sources.

[WardCunningham]

Find some way to allow hovers to work when data is coming from sources such as the 5-star plugin as in this example.

We've shown that these features worked for the MSI data.

I’ve located the original source when these features were programmed starting on March 26, 2012.

I’ve discovered in order for the hover to work it must come from a dataset with the column headed “Material Name”. Sounds rater specific to what I was working on in 2012.

Likewise footnotes need to appear in a column headed “comment”.
