//! An abstract interface defining a fitness landscape
/*!
A "fitness" landscape defines the environment in which an
organism competes for survival. A class implementing this
interface will test each organism in a list against some criteria.
The landscape is tied to the nature of the organism; think of an
organism as a potential solution to a problem posed by the landscape.
A floating-point organism, for example, could be tested by a fitness
landscape that represents a function to be maximized. Or, an organsism
describing the shape of wing could be tested by a landscape
implementation that understands airflow.
