* TTextHighlighter class.
*
* TTextHighlighter does syntax highlighting its body content, including
* static text and rendering results of child controls.
* You can set {@link setLanguage Language} to specify what kind of syntax
* the body content is. Currently, TTextHighlighter supports the following
* languages: ABAP, CPP, CSS, DIFF, DTD, HTML, JAVA, JAVASCRIPT, MYSQL, PERL,
* PHP, PYTHON, RUBY, SQL, XML and PRADO, where PRADO refers to PRADO template
* syntax. By setting {@link setShowLineNumbers ShowLineNumbers}
* to true, the highlighted result may be shown with line numbers.
*
* Note, TTextHighlighter requires {@link THead} to be placed on the page template
* because it needs to insert some CSS styles.
