add plot format comments to indometh example
add g3geoms.  works
added g3stats, works
remove old geom code
split out functional, patterns and d3 extensions. works
clear errors before new plot.  also encoding change
add identity function to g3functional
disable node title while I work out how X works
bad commit
bar geom keys off cluster instead of X.  This isn't going to work if there are multiple Xs or no Xcluster.  Should fix.
plots use xcluster.  mpg is broken.
make aestheticUtils into a package.
add non-functional aesthetic tests
use d3.scale.identity instead of a custom one.
wrap up svgtransform translation in a function
separate and temporarily deactivate key functions.  This is because data(,key) only works if the key uniquely identifies the node, and the public datasets often dont.

What's a key for? animation, mostly, so it won't be missed soon.
add helpful comments to hieraxis builder
voodoo tweak to hieraxis.  The scaling / positioning of the hieraxis is just plain WRONG for cluster list length = 1
Nasty tweak to labelling code.  Must fix.
Tweaks to data() plots
