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

* Improve ParticleEmitter interface.

---------------  ACTUAL PROGRESS  ---------------
	
* Worked with Rock in revamping ParticleEmitter interface:
  - Added Spawn() function with more intuitive controls.
  - Computation of spawn directions given a direction and spread angle.

* Added Spawn() function.  Spawn() now takes care of creation of particles
  rather than Update() function.  Update() now just updates particle values
  and frees dead particles.

* Cleaned up RecyclingArray class for more effecient management of array
  elements.  Deleted elements are swapped with last alive element in array,
  which eliminates a search for next free element when getting new element.
		
---------------       SNAGS       ---------------

N/A

---------------       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...).
