Detailed Description

Edge defining the cost function for limiting the translational and rotational acceleration at the end of the trajectory.

The edge depends on three vertices , an initial velocity defined by setGoalVelocity() and minimizes:
.
a is calculated using the difference quotient (twice) and the position parts of the poses
omegadot is calculated using the difference quotient of the yaw angles followed by a normalization to [-pi, pi].
weight can be set using setInformation()
penaltyInterval denotes the penalty function, see penaltyBoundToInterval()
The dimension of the error / cost vector is 2: the first component represents the translational acceleration and the second one the rotational acceleration.

Remarks:

Do not forget to call setTebConfig()

Refer to EdgeAccelerationStart() for defining boundary (initial) values at the end of the trajectory
