Have towers exploit heal lopsided creeps

[CarsonBurke]

• Calculate the efficacy of heal considering its spread across a squad
• Coordinate towers to force lopsided healers to heal themselves, allowing us to deal more effective damage
• use eventLog to see what the heal() distribution is. Exploit consistent focussed healing
  • divide squad's heal strength by member count - heal targets

Do you plan to add it to defending creeps as well? This works great for invaders too.
