--------------- EXPECTED PROGRESS ---------------

* Add functions to set render states specific to Particle System, while 
saving and restoring render states before and after rendering particles. 

* Add functionality to particle emitter class to properly handle 
projection matrices so that particles are displayed correctly.  

* Create specialized particle emitters to achieve desired for game 
aesthetics.

---------------  ACTUAL PROGRESS  ---------------
	
* Successfully added code in ParticleEmitter class to save, set, and 
restore render state blocks cleanly.

* Tried to make particle emitter demo "perrrty".

* Experimented with particle parameters to properly scale and display 
particles without too much blurring.

* Added various class members needed or helpful in interfacing.

* Added demo and implementation of derived emitter class for collision effects.
Added it to project (ParticleSystems.h).
		
---------------       SNAGS       ---------------

* Discovered that calling SetRenderState() and setting D3DRS_POINTSIZE_MAX 
to a value that surpasses the limits of the card results in failure when 
calling ApplyStateBlock().  Fixed by leaving value at default.

---------------       PLANS       ---------------

* Create specialized particle emitters to achieve desired for game 
aesthetics.

* Possibly start adding particle emitters members to game objects 
(i.e. ships, planets, etc...).
