Improve CCA barplot performance for datasets with > 100 variables.

[tshead2]

Regrettably, our fabulous D3 animation bogs-down when switching CCA components for datasets with large numbers of variables (on the order of 100 or more).

Look at how we can improve performance if we remove the animated transition. Simply removing the transition doesn't seem to be sufficient, but maybe we could speed things up by removing D3 entirely and using CSS to hide / show the positive and negative bar columns. Maybe we could use CSS animation to do this in a way that scales.
