replace ground prefab with a gameobject and sprite collection
moved zombie attacks to seperate script
removing Library/ScriptAssemblies/* from vc
fixed things after not saving the project (now zombies change z values?)
fixed issue (zombie was starting out slightly overlapping table)
added a lazer beam (push f to fire)
Player attacks now deal damage to zombies rather
    than zombies detecting damage. The
    PlayerProjectile script does this, and lets
    you specify the damage, whether the projectile
    should disappear when it hits (bullet), keep
    being displayed but only deal damage once (sword)
    or deal damage multiple times (for the newly added
    lazer beam).
