 * This file defines the syntax of OGNL, the Object-Graph Navigation Language.  This
 * language was devised by Drew Davidson, who called it Key-Value Coding Language.  Luke
 * Blanshard then made up the new name and reimplemented it using ANTLR, refining and
 * polishing the language a bit on the way.  Drew maintained the system for a couple of
 * years; then Luke converted the ANTLR grammar to JavaCC, to eliminate the run-time
 * dependency on ANTLR.
 *
 * See package.html for a description of the language.
