/**
* jEdit's text area component. It is more suited for editing program source
* code than JEditorPane, because it drops the unnecessary features (images,
* variable-width lines, and so on) and adds a whole bunch of useful goodies
* such as:
* <ul>
* <li>More flexible key binding scheme
* <li>Supports macro recorders
* <li>Rectangular selection
* <li>Bracket highlighting
* <li>Syntax highlighting
* <li>Command repetition
* <li>Block caret can be enabled
* </ul>
* It is also faster and doesn't have as many problems. It can be used in other
* applications; the only other part of jEdit it depends on is the syntax
* package.
* <p/>
* <p/>
* To use it in your app, treat it like any other component, for example:
* <p/>
* <pre>
* JEditTextArea ta = new JEditTextArea();
* ta.setTokenMarker( new JavaTokenMarker() );
* ta.setText( "public class Test {\n" + " public static void main(String[] args) {\n"
* + " System.out.println(\"Hello World\");\n" + " }\n" + "}" );
* </pre>
