Added
- `FuelDatabase` class to replace the `Scenario` class
- Fuel descriptor is used to access fuel in the database instead of index
- cli for fuelmap (list fuel databases and fuel classes)
- cli for postprocessing (rearrange netcdf file to store fire fields in 2D instead of 3D)
Changed
- all add_patch functions have been splitted into more explicit functions.
For example: `addRectanglePatch` has been splitted to `add_fuel_rectangle_patch`, `add_unburnable_rectangle_patch`, and `add_ignition_rectangle_patch`.
- Update examples
- use __str__ instead of show methods for `FuelProperty` and `BaseFuel`.
Deleted
- `Scenario` class is not used anymore
