*) main method is generalization of main method of ymageFontGenerator:
it does not matter how many lines of how many bits a font is made of
as long as the values stay the same within the font -> use this class as
a template for your own font generators and be a happy camper
*) main method checks if font is valid (96 characters, all letters must have
same number of lines and same number of bits per line)
*) ***** I have not checked if the result is really a valid font so far. *****
