 The file would use the .level file extension.

+The file can contain anything, the used data is enclosed between a header and a footer.
+This could be used to add: musics, images and other stuff in the level file itself 
 
 Only one Header and One Footer should be present in the file.
 The parser will only read the first one it finds so to avoid problem, it is best practise to put the
 level data at the top of the file.
 
-- The HEADER will be defined by the characters 'S', 'M', 'S'
