added simplistic Agv support

[liquidcronos]

Description

In order to simulate interactions between robots and intralogistic systems a simple agv class was setup that is meant to simplify agv simulations.
A base template class was developed for different kinematics and a differential drive kinematic childclass was implemented.

Motivation and Context

This change is needed to simulate production cells where the workpiece is delivered by an intra logicstics system in this case an agv.

How has this been tested?

Each class method has been unit tested against precomputed values.
