* See: http://en.wikipedia.org/wiki/Seven_segment_display
*
* Notation: +-a-+

*
* Usage:
*
* Register a map variable, and fill it with a character set:

*
*
* Then use for conversion:
* seg7 = map_to_seg7(&map_seg7, some_char);

*
* In device drivers it is recommended, if required, to make the char map
* accessible via the sysfs interface using the following scheme:
