Add Planet dependency to MarsRover and create a Mars planet with a 10x10 grid. Update all existing tests to compile.
Add failing Unit Tests for testing the wrapping functionality
Implement wrapping functionality and remove tests that assert minus 1 as this is no longer a valid coordinate. These cases are now covered in the WrappingUnitTests.cs file.
Move Unit Test files into UnitTests folder
Add Obstacles to IPlanet. Add failing Unit Tests for Obstacle checking.
Implement obstacle checking on MarsRover
Rename MarsRover private variables _x, _y and _direction to currentX, currentY and direction as I feel they read better
