------- Additional Comments from Francisco Tolmasky <tolmasky at gmail.com>
Made it so that most the functions now match the behavior of Shark. Most
notably, in the heavy view, child nodes now represent the statistics of the
root node, but in the callstack originating at that node. Also added a number
of performance improvements, making it so the heavy tree is not calculated
until its nodes are revealed. Moved a lot out of C++ and into JS, allowing for
more representations and easier manipulations in the future.
