* asteroid now working reasonably well. Hexagon finite element modelling working. no hit testing as yet.

* ship has modified tick event and acceleration method. trying to drag as much as possible back in to relevant classes rather than things being in global scope. not quite there yet.

* Bullets now working. No hit testing or bounds testing.

* just introduced "space" class. This will act as a container for all other elements, rather than objects being dropped direct at the root of the stage.
