Added the KnotPoint.msg
Added the KnotPoint class
Updated ramp_planner and path_modification with the KnotPoint class and msg. TODO: Update the other packages, trajectory_generator and ramp_debug
Changes made to integrate KnotPoint class and msg into the packages
Trajectory generation has been tested, but entire planner has not been tested yet
Fixed a bug where the updatePopulation method was not setting the new paths of the trajectories. This was causing the planner to crash once the control cycle started.
Also, robot 2's IP changed to 192.168.1.102. Why? I don't know, but I changed the address in the launch files.
