8 Segment LED

Support for an 8 segment LED display.
An 8 segment LED display provides the capability of a single digit on a typical desktop calculator. The 8 segments are made up from 7 vertical or horizontal bars and a decimal point.
These 8 elements are labelled from 'a' to 'h' as follows:-
|    |
f    b
|    |
|    |
e    c
|    |
--d--- h
Each of the above elements is turned on or off using an output pin. So we require 8 output pins to control the led segment.
WebbotLib allows us to either turn individual segments on and off or write a character.
