Tricky Bits and Gotchas

• apmatrix of Fish -- need default fish ("undefined fish") to represent "no fish"

• Environment AllFish returns clones -- this leads to need for Environment Update

• Display algorithm traverses both 2-D matrix and 1-D vector (this solution is easier to justify with an unbounded ocean)

• Program should really have more than one sort (display order and "current"/processing order)

• Two variations of RandInt: r.RandInt(2) vs. r.RandInt(0, 1)

• RandGen internals: treat as black box!

• setw in Display: not in AP subset (I think), but useful if you set WIDTH to 3 (another recommendation: use '~' for empty spaces)

• Display needs to change for unbounded ocean
