Log message:
Add skeleton to fill in with collision detection code.  Added is_solid
attribute to objects (collision detection will not be performed between
objects iff neither has is_solid == true).
Add a stub documentation file to fill with technical documentation, as and
when I have the inclination / inspiration.
