• Develop an api that moves a rover around on a grid.
• You are given the initial starting point (x,y) of a rover and the direction (N,S,E,W) it is facing.
• The rover receives a character array of commands.
• Implement commands that move the rover forward/backward (f,b).
• Implement commands that turn the rover left/right (l,r).
• Implement wrapping from one edge of the grid to another. (planets are spheres after all)
• Implement obstacle detection before each move to a new square. If a given sequence of commands encounters an obstacle, the rover moves up to the last possible point and reports the obstacle.
• Example: The rover is on a 100x100 grid at location (0, 0) and facing NORTH. The rover is given the commands "ffrff" and should end up at (2, 2)

Tips: use multiple classes and TDD
