Tripping is the phenomenon of trying to edit a collection while it is
already being iterated through (self-defined). Cells will no longer
trip as Neurons (and eventually all Cells) no longer tick() each other.
Some functionality was added to tick() to better simulate a cell (food
depletes over time). Some functionality (namely the firing of action
potentials) was also moved out of tick() into excite(). This should set
a precedent for actions that are “quick,” and only require an immediate
signal from another cell to execute.

The dead boolean field keeps track of whether or not the cell is
apoptosed. It is a safety feature which maintains that cells cannot
function ALTHOUGH THEY MAINTAIN SOME ATTACHMENT TO THE NETWORK.
apoptose() now only removes children from the dead cell, however, it
should remove itself from its parents’ children and its children’s
parents.

Stylistic tweaks and much documentation also added. Refactored slightly.
