The basic functions for letter detection have been implemented, but the main function of this system is not functional at all.

We need to check that the startColomn and endColom are set to the correct value (currently this is not the case).

We also need to see how to adapt the value at which we consider that there are potentially interesting characters (calculate the minimum amount of white to have to trigger the function).

For the moment, the current state of the branch on commit a0351ba is only a working base but not at all something functional, apart from the auxiliary commands to get the color of a pixel, save the image in BMP or load the image in BMP.

The logic of the letter detection function has been reviewed and simplified: :

• There are now 2 auxiliary functions to detect when a line is predominantly composed of black pixels or predominantly of white pixels (depending on the program's needs).
• The logic of the main function has been revised to make it clearer, and to ensure that the image of the detected letter is recorded on every pass.

For the moment, the code isn't working, as the pixel average remains at 0 for no reason.
