[WIP] Big Refactor

[MaximeBouton]

AutomotiveDrivingModels.jl Refactor

PR to refactor the structure of the package. Assign yourself to some tasks by editing this description.

For each new folder we should:

• import the relevant piece of code from the current repository
• open issues if you notice something weird or inefficient and we will fix it at the second pass
• write tests
• write doc strings
• write a documentation page

New folder structure : folder (dependencies)

• Roadways (no deps): roadway definition, roadway generation, projections, frenet frame
  • code moved
  • test written
  • doc written
• VehicleDefinitions (no deps): abstract type, interface, current vehicle definitions - Raunak
  • code moved
  • test written
  • doc written
  • Question: Should we change the name to reflect Samantha Kim's comment ref. pedestrians
    should not be called vehicles. Further, should we include bicyclemodel with CAR, TRUCK etc
    as opposed to being a standalone thing as it is now?
• States (roadways, agent definitions): current states definition and scenes - Raunak
  • code moved
  • test written
  • doc written
  • Question: What is the correct way to test constructors for example VehicleState and
    associated Base.show and Base.write methods?
• CollisionCheckers (states, agent definitions): collision checking utilities
  • code moved
  • test written
  • doc written
• Actions (roadway, states, agent definitions): interface, current action definitions
  • code moved
  • test written
  • doc written
• FeatureExtraction: current feature extraction tools, helpers function to get neighbors and lane info
  • code moved
  • test written
  • doc written
• DriverModels (roadway, states, actions, features): interface, current driver model
  • code moved
  • test written
  • doc written
• Simulation: simulation , callbacks
  • code moved
  • test written
  • doc written

After the first pass:

• make sure the tutorials still runs
• we should tests other project on this branch of AutomotiveDrivingModels.jl,
  since this is just a refactor nothing should break.

Questions

• Should we reexport Vec?
• Should we reexport Records?

Notable changes

A lot of files are unused, we should not include them in the refactor. If they might be useful in the short term, just open an issue.
No 1d/2d splitting.
Rename filenames if it is relevant.

@raunakbh92 Could you take a look at the agent definition interface I just pushed ?
