sub-command. This will will turn the ScenarioChecker on or off for the command
line. If the Checker detects an error the simulation will not be executed.
-`TopographyCreator` added functionalities:
- move all topography elements by some dx, dy [issue#171](https://gitlab.lrz.de/vadere/vadere/issues/171)
- move the whole topography by some dx, dy [issue#148](https://gitlab.lrz.de/vadere/vadere/issues/148)
- automatically merge overlapping obstacles by using the weiler algorithm.
-`Processors`:
- new processors to compute the fundamental diagrams (by using different velocity, flow and density measurement methods)
-`GUI`:
- improved coloring
-`OutputFile`: Distinguish between indices (rows) and headers (columns), in code and with a new checkbox that when enables allow to write meta-data into output files. Furthermore, resolve naming conflicts (if they occur) in headers of output files (see #201).
