[crunchstat-summary] zoom/pan should be synchronized for all HTML graphs
Currently the four graphs in the HTML plot are zoomed and panned independently. This should be synchronized, locking the X axes together for all of them.
Example code available here: https://github.com/danvk/dygraphs/blob/master/src/extras/synchronizer.js

Need to add synchronizer.js to MANIFEST.in (otherwise it doesn't get packaged)
Is synchronizer.js modified from the original source (other than by adding the attribution)? Maybe mention the git commit in case we ever need to update it.
MIT license requires copyright notice and license text. In case this is considered a "substantial portion" I'd suggest pasting https://github.com/danvk/dygraphs/blob/master/LICENSE.txt into a comment in synchronizer.js.
As for the actual content -- tested & works, LGTM.
