Maze solver

Same as Brazilian-Institute-of-Robotics/doogie_base#17, you will need both these changes in order to properly build the project.

I tested both launches files and they're working well. I found a bug in the rviz interface but I will describe it better in an issue. I noted also the robot with a big jerk at the start of movement when it moves straight. Finally, I think there are so many "INFO" when running the move base node. Maybe we can change for "DEBUG" verbosity level (comment valid for New Move Base #17)

Without these notes, the simulation is working well and smoothly. I ran it a few times and I haven't any error. Great job!!!

Good point. I've tried to reduce all ROS_INFO* calls, but would be great changing those to "DEBUG" level. Only problem I see is that we are missing an easy way to enable the debug mode (and display debug msgs), maybe would be better addressing this in a next PR. I'm raising an issue to keep track of this (#6).
