Mars Rover Kata

This is a summary of the behavior of the rover that we'll implement:

It's located on a grid at some point with coordinates (x,y) and facing a direction encoded with a character.
The meaning of each direction character is:
- N -> North
- S -> South
- E -> East
- W -> West
The rover receives a sequence of commands (a string of characters) which are codified in the following way:
- When it receives an f, it moves forward one position in the direction it is facing.
- When it receives a b, it moves backward one position in the direction it is facing.
- When it receives a l, it turns left changing its direction (by one step in the direction).
- When it receives a r, it turns right changing its direction (by one step in the direction).

TDD is mandatory :-)
