Removed ability for plane to check weather
Plane class refactored
Airport can grant plane with permission to land
Airport can grant permission to take off
Added test context for taking off and landing
Airport knows when it is full
Airport does not let plane land if it is full - error raised
Air traffic control only lets planes take off in sunny weather conditions
Airport won't let plane land or takeoff in stormy conditions
Airport won't let plane take off in stormy conditions
Refactored code
Dealing with merge conflicts, I hope...
