We need to show a summary of multiple plots. This could be as simple as a
constancy table, and/or a matrix of plots vs. species with cover values.

There are some issues to consider:
1) similar taxa and lumping of varieties into species
NOT ADDRESSED
2) how to select plots efficiently in the viewer: datasets could be one source,
but ideally we'd have a 1-click solution for a single CEGL
DONE pick a CEGL, search results, or dataset
3) For CEGLs, which plots to use as source: how far off for fit to use, base it
on number of plots classified??
DONE can use just good fit or all plots.
4) What cover value to use, average of raw percents ... convert back to cover
code or leave as percent?
DONE both.
