Detailed Description

Edge defining the cost function for limiting the translational and rotational velocity according to x,y and theta.

The edge depends on three vertices $\mathbf{s}_i, \mathbf{s}_{ip1}, \Delta T_i$ and minimizes:
$\min \textrm{penaltyInterval}( [vx,vy,omega]^T ) \cdot weight$ .
vx denotes the translational velocity w.r.t. x-axis (computed using finite differneces).
vy denotes the translational velocity w.r.t. y-axis (computed using finite differneces).
omega is calculated using the difference quotient of both 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 velocity w.r.t. x-axis, the second one w.r.t. the y-axis and the third one the rotational velocity.
