New Seven Segment library !!

Hello everybody !! I just made a library that can control a 7-segment display. Yes, only one.. But soon I'll be making a version 2 with multiple displays !! For more info about the library, go to the "Keywords.txt" file.

Link to the library : My Files

P.S.: Sorry for my English errors.. Feel free to correct me :wink:

What's it assume for hardware to drive the 7-segment?
Discrete IO pins?
Shift register(s)?
MAX7219?
