Added a KeyManager class to handle key presses and the like

Pretty simple, works well.
Created PhysicsShape

Added operators to Particle - avoid, they map to Vector operators which
are kinda slow
Created PhysicsShape and the Point PhysicsShape.
Forgot to save project before committing
PhysicsShape library almost complete

Only Box intersect Ellipse to go.
Finished the collision detection methods, now to implement
Seems to still work :P
Done for now, need to add PhysicsClasses to Entities

PhysicsClasses will determine what collides with what and what events
take place on collision
Collision detection is working

Couple bugs.
One what is the ring of bullets that appears when the time passes
integers?
Two why does collision detection not work properly with time rewind?

Plans:
rework the time system to use GameEvents or sth like that.
Created GameEvent

Reorganized GameLib into folders and namespaces.
Switching over from AdvancedEntityManager to GameEventManager

Most of the logic for which entities were displayed and such resided in
AdvancedEntityManager, however now most of it will be in GameEvents
which are managed by the GameEventManager in much the same way entities
were under AdvancedEntityManager.
Continuing to switch over. Certain events are unprocessed still

Fixed large bug in Add method of LayeredLinkedList. Should be bug-free
now...
Continuing to debug
Continued Debugging

Added LayeredLinkedList.ElementsBetweenBackwards
Added a test of LookupLinkedListSet
Changed GameEvent to a class
Added a Contains method to EntityManager
Many changes to GameEventManager for debugging purposes
Switched the invisibility thing to use an event
Shift slows down the rate at which the time rate changes
Fixed obvious bug in ElementsBetweenBackwards

also added debug prints to make invisible and rewind make invisible
More debugging - FOUND BUG!!!!!!

Error was in LookupLinkedListSet

refnode.Value should have been refnode, forgot to change when
eliminating Reference
Removed debug statements

Only (obvious) bug left is the weird rings that appear every second
Removed another debug statement

Minor change

Plans.txt describes my future plans
Updated Plans.txt
Figured out approximately where error lies

Must have something to do with introduction of PhysicsShape.
