* Removed spam-like warnings (mostly replaced by printing a single warning counter)
* Removed inst_runtime_interval() from latency_graph.py as it was out of that file's responsibilities. Moved into TrCallbackInstance directly
* Fixed coloring of latency graph (planning was misspelled)
* Removed papermill cell headers (prevented cell magics from working)
* Changed bisect to bisect_right because of Python's name resolution acting stupid
* Print exceptions when building message trees
