TnT Tree

This example is forked from Collapsible nodes.

This framework is awesome but i still feel very strange while using d3.selection.classed() function, for some of the path selections can not attach one specific class name. Very odd behavior!

More information relate to Newick Format please reference Wikipedia and TnT tree API.
