/**
 * A simple example showing how to add and use Code Templates to an
 * RSyntaxTextArea.<p>
 * 
 * A "code template" is a kind of macro for commonly-typed code. It associates a
 * short identifier with a longer code snippet. When code templates are enabled
 * and a short identifier is typed, it is replaced with the corresponding longer
 * code snippet. Type Ctrl+Shift+Space to insert the template.<p>
 * 
 * This example uses RSyntaxTextArea 2.5.6.
