Support for different agent models

[YueZhang-studyuse]

Currently the agent model is implicit, it supports forward displacement of one unit, and it supports rotation by 90 degrees. We want to make the model explicit and to describe the actions in a text file.

sketch:

• plan symbol followed by drawing instruction (rotation, displacement).
• the shape of the agent on the grid (square or round plus radius, other abstract shapes made of simple squares).
• the drawing instruction are keyword followed by numeric parameters.

Example:
MODEL [name (eg. MAPF, MAPF_T)]
SHAPE [circle | square | sprite file] [radius]

[PLANSYMBOL]
ROTATE [radians]

[PLANSYMBOL]
DISPLACEMENT [delta x][delta y]

[PLANSYMBOL]
ROTATE [radians]
DISPLACEMENT [delta x][delta y]

Re-prioritised for 2025.

I assume this is also solved in round 2026 because we are using a rectangular safety bubble to do collision checking?
