doodlebug
=========
Project inspired by Walter Savitch's 2014 C++ textbook. This program
essentially answers Chapter 16, Question #9 of
_Problem Solving with C++_ (ninth edition).
Overview
--------
The goal for this project is to create a simple two-dimensional
predator-prey simulation. In this simulation the prey are ants
and the predators are doodlebugs. These critters live in a world
composed of a 2D grid of cells. Only one critter may occupy
a cell at a time. The grid is enclosed, so a critter is not
allowed to move off the edges of the world. Time is simulated in
time steps. Each critter performs some action every time step.
You should see a cyclical pattern between the population of
predators and prey, although random perturbations may lead
to the elimination of one or both species.
Usage
-----
Run `make run` to build and run the C++ program, starting the
simulation.
% make run
Grid created.

Graph
-----
Run `make graph` to show a graph of the organism counts over a
given number of iterations.
