simobject.h

/******************************************************************************

This is the super-class for almost all twodee classes. It is quite
simple. It simply contains a couple of public accessible methods. Its
main feature is that it uses recursive parent-child
relationships. This allows for events such as keypresses, a new
simulation cycle, and rendering to be done recursively. 

It also allows all objects to have distinct names - and invaluable
tool for debugging.
