Detailed Description
Edge defining the cost function for limiting the translational and rotational acceleration.
The edge depends on five vertices 
and minimizes: ![$ \min \textrm{penaltyInterval}( [ax, ay, omegadot } ]^T ) \cdot weight $](form_4.png)
.
ax is calculated using the difference quotient (twice) and the x position parts of all three poses
ay is calculated using the difference quotient (twice) and the y position parts of all three 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 3: the first component represents the translational acceleration (x-dir), the second one the strafing acceleration and the third one the rotational acceleration.
