Parameterize the trajectory by time.

This is where the velocity profile is generated.

The derivation of the algorithm used can be found here: http://www2.informatik.uni-freiburg.de/~lau/students/Sprunk2008.pdf

Parameters

points	Reference to the spline points.
constraints	A vector of various velocity and acceleration constraints.
startVelocity	The start velocity for the trajectory.
endVelocity	The end velocity for the trajectory.
maxVelocity	The max velocity for the trajectory.
maxAcceleration	The max acceleration for the trajectory.
reversed	Whether the robot should move backwards. Note that the robot will still move from a -> b -> ... -> z as defined in the waypoints.

Returns

The trajectory.
