began implementing Arrow class and projectile code
shots fired! arrows now being shot from hero
Arrows now projecting from hero; needs refactoring
made arrow a subclass of entity
nullPointer is currently plaguing this
NullPointer fixed. arrows now firing

the dungeon need to be instantiated in the Arrows constructor
arrows fire upon release in all directions 

the keyRelease() method had to be added in MainGameState because only
MainGameState implements KeyListener
melee damage on enemies, enemies blink

added a keyPressed() to MainGameState
also added an image to indicate the melee animation
press B for melee attempt
Arrow count is now drawn in the HUD (menu class)

also cleared out some of commented code
Melee attack damages enemies in all directions
