added some functions to format the youtube URL into an embeddable format so that it can be used to create the experiment CSV
chnaged member variable naming scheme to match roscpp, added copies of the start and end waypoints so that it appears for longer
tweaked visualization config
factored functions out of this into experiment utils source
added utility functions for doing things regarding experimental setup and creation
added make rules for experimental utility functions
tweaked camera move speed, and added a commment line
regenerated results for testing
added make rules for the trajectory video lookup class
this class should save me a lot of headache because it holds a lot of the rosbag reading and writing and trajectory+video pairing management code; way less painful now
removed all rosbag and trajectory-video lookup code and making use of new class to handle it
