• Add additional Huggable classes such as:
• Trees
  • needs crazy amount of hugs by default
  • does not give hugs back
• Cats
  • only ever accepts a single hug and could care less about expressing love
  • never hugs dogs
  • sometimes hugs other cats
  • sometime people
  • gives twice as many hugs to trees
• Dogs
  • only ever needs a single hug to reach full love
  • sometimes hugs cats
  • always hugs people
  • likes to pee on trees (does that count as a hug?)
• convert existing LostSoul class to People class
