* Added option to inherit the robot footprint model from the costmap_2d footprint by setting footprint type to `costmap_2d` (thanks to Alexander Xydes).
Note that using a polygon as a robot footprint model is computationally more expensive than using two circle or line models.
* Fixed issues in fd discretization grid and graph consistency
* Fixed initialization of linear velocity output commands in simple car and unicycle models (thanks to Thomas Denewiler).
* Fixed wrong parameter namespaces for some grid parameters
* Replaced non-ASCII characters in python script
* Added find_package script for osqp in case control_box_rst is linked against it
