Note: At the time I originally made this, I didn't know that this was actually how a C++ compiler implements single inheritance.
Basic OOP with single inheritance in C in 5 lines
The implementation.c file's comments show most of the "features"
This is mainly an excersise in making a quick and simple OOP system.
If you can think of something insightfull to do with this little system feel free to give me a buzz.
