Version 1 - base whale model on zooplankton model
Version 6 - bigger whales
Version 7 - removed unneeded graphs
Version 7.2 - Liz + Shar's changes:
1) Add moveable Camera so that the ecosystem is easier to see. Users can move the Camera up and down, right and left, and backward and forward to get better views (arrow keys, WASD, and R / F to rise / fall).
2) Make whales a bit smaller. For this patch of ocean, the whales are storing more carbon in life and in death than the phytoplankton and zooplankton are.
3) Add just one whale at a time instead of 5 at once. This allows the bumps in the graphs to be easier to see, and is more realistic if we are thinking of this as a small patch of ocean.
4) Modify the rate at which whales are 'eaten' as they fall as it was. This ends up with whales losing about 2/3 of their carbon as they fall.
5) Move whales up so their mouths are aligned with the phyto/zooplankton.
6) Remove phytoplankton turning red when respiring, to be consistent with the Phyto/Zooplankton Model.
