Fixed localization algorithm
Included map resolution + moved variables

General variables for the robot (distance between the wheels, diameter
of the wheels) and the map (resolution of the squares) have been moved
from localization.h to another file (utils_params.h) to be more
accessible

Map position and Real position, Cardinal point

IMPORTANT : I changed the function to get the direction of the robot
from 'get_d' to 'get_w', and this function returns now a double from 0
to 360 degrees.
The functions 'get_x' and 'get_y' now return the values encoded with the
map resolution. Furthermore I added several functions to get the real
values for X and Y (in mm) called 'get_realX' and 'get_realY', and a
function to get the cardinal point of the direction of the robot. For
more, read comments in 'localization.h'.
