Performance for traverse function

[dmarzo]

I have performance leak (navigator freeze) when have 5k rows and same names. I resolved problem adding unique counter to url, instead of: while (me.nodesByUrlToken.hasOwnProperty(node.urlToken)) {node.urlToken += '-';}

bubbletree.js

• (ln 185) urlTokenSource += '-' + me.globalNodeCounter;

But create weak url token that depends on row order.
