/**
* Scanner for the Tcl programming language.
* <p>
*
* This implementation was created using <a href="http://www.jflex.de/">JFlex</a> 1.4.1; however, the generated file was
* modified for performance. Memory allocation needs to be almost completely removed to be competitive with the
* handwritten lexers (subclasses of <code>AbstractTokenMaker</code>, so this class has been modified so that Strings
* are never allocated (via yytext()), and the scanner never has to worry about refilling its buffer (needlessly copying
* chars around). We can achieve this because RText always scans exactly 1 line of tokens at a time, and hands the
* scanner this line as an array of characters (a Segment really). Since tokens contain pointers to char arrays instead
* of Strings holding their contents, there is no need for allocating new memory for Strings.
* <p>
*
* The actual algorithm generated for scanning has, of course, not been modified.
* <p>
*
* If you wish to regenerate this file yourself, keep in mind the following:
* <ul>
* <li>The generated TclTokenMaker.java</code> file will contain two definitions of both <code>zzRefill</code> and
* <code>yyreset</code>. You should hand-delete the second of each definition (the ones generated by the lexer), as
* these generated methods modify the input buffer, which we'll never have to do.</li>
* <li>You should also change the declaration/definition of zzBuffer to NOT be initialized. This is a needless memory
* allocation for us since we will be pointing the array somewhere else anyway.</li>
* <li>You should NOT call <code>yylex()</code> on the generated scanner directly; rather, you should use
* <code>getTokenList</code> as you would with any other <code>TokenMaker</code> instance.</li>
* </ul>
