Inconsistency between MultiObjectTracker params and instantiation in mapper.py

[Xiaohao-Xu]

Thank you for this insightful project! I really appreciate the effort put into the examples. However, I encountered an issue when trying to run the examples. There seems to be an inconsistency between the parameters expected by the MultiObjectTracker class and how self.mot is instantiated in the mapper.py file.

Additionally, I could not find the motion model being defined or passed to the MultiObjectTracker instance in the provided example code.

Could you please address these inconsistencies to ensure the examples can be executed successfully? Providing the missing motion model (or clarifying where it should be defined) would also be helpful.

Thank you for your time and efforts in maintaining this project. I look forward to your response.
