Big code dump: prototype code for the new clustering visualization.
Updates of most infrastructural libraries.
Slight function arg tweak.
Initial integration of the new floaty-circle code into the clustering visualization. Most functionality is there, minus distinguishing phrases; aesthetics are still something of a mess.
Most of the significant-phrase logic.
Working distinguishing phrases.
Grafting the prepopulation logic back on.
Bug fix to make phrases show up properly on initial phrase load for currently selected circle, plus some performance improvements.
Closer-to-final clustering presentation: curly braces have arrived. Some slight breakage in Firefox, though, unfortunately.
Fix for some strange and hard-to-detect firefox behavior: apparently SVG bounding boxes in Firefox change over time as their contents change; I don't think this is to-spec.
Braces and S-curves to connect cluster circles to the phrase box.
Margin adjustment on the visualization.
Typo fix, plus some pretty connecty-line things.
More color tweaking, plus some style changes, and dates and breadcrumbs.
Strike through the description text until we have final copy.
