/**
 * LinearSearchDictionary.java
 * Jeff Ondich, Carleton College, 2014-01-01
 *
 * An implementation of the WordGameDictionary interface using a sorted list.
 *
 * This implementation is part of an introduction to Java interfaces in
 * Carleton's CS 201 Data Structures course.
 *
 * NOTE: I use the "this." notation in this sample since you're moving
 * from Python (which has "self.") to Java. In fact, I actually use
 * "this." routinely in my own Java code, but that makes me quite
 * weird. The vast majority of Java programmers omit "this.".
