broken attempt to impute classes
imputing classes WIP but at least every Thing hatched

class hierarchy flat
Thing not shown in taxon_picker
some node coloring problems
full success gated by incomplete ontology
Thing now root of hierarchy WIP taxon_picker incompletely colored and buggy
converted all pickable .nq files WIP taxon_picker and sub/super overriding
WIP Taxon.get_instances() now hierarchic but clicking abstract taxons still weird
keep set_ and taxon_picker side-by-side
WIP trying to get the original test suite working again
WIP: so very broken
cowtest working and integrated into test.html.eco but WIP completely without huviz
WIP cow tests still working, getting huviz fully converted to require()
WIP mocha and huviz both running but still with cow tests
WIP removed cowtest references from frontend, got huvis.html and tests.html reasonable, but sync testing failing
move constructor to top of GraphCommand
WIP hmm tests seem to work but why is the graph left in the state it is
put test suite in a jquery-ui dialog box
format the test suite within its dialog and restore the huviz controls
remove all residual cow test stuff
fix up mocha formatting
at /tests among the prod, beta and alpha links
interlink test and orlonto pages, improve formatting
