Develop an API that moves a rover around a grid

Rules

• You are given the initial starting point (0, 0, N) of a rover
• 0,0 are X,Y coordinates on a grid of (10, 10)
• N is the direction it is facing (N, S, E, W)
• L and R allow the rover to rotate left and right around the grid
• M allows the rover to move one point in the current direction
• The rover receives a char array of commands e.g. RMMLM and returns the finishing point after the moves e.g. 2:1:N
• The rover wraps around if it reaches the end of the grid
• The grid may have obstacles. if a given sequence of commands encounters an obstacle, the rover moves up to the last position and reports the obstacle e.g. O:2:2:N
