table view of node execution data

[mjkkirschner]

should include following features:

• [ ] columns: time(ms or s), NodeType , NodeName, % of total
• [ ] - potential columns (number of times function was replicated - this is essentially callsites)
• [x] sort column by ascend / descend

[mjkkirschner]

current images seem to have too much precision to easily be compared - I'm not sure we really have real accuracy under 10 ms anyway.

sort column by ascend / descend has been finished by @ScottAMitchell , still missing other feature set
