 * Defines the interface for a fitted straight line.
 * 
 * There are many methods for fitting a straight line of the form y = A + Bx
 * to n paired observations (x, y). This defines the common interface for classes
 * that fit such lines.
 * 
 * This interface is similar to the eponymous interface in the Java Statistical Classes
 * library, but it is reimplemented from scratch to avoid license restrictions.
