/**
 * Custom Tag class to access the {@linkplain com.fredck.FCKeditor.FCKeditor container}.<br>
 *<p>
 * <b>Simple usage</b>:
 * <pre>
 *	&lt;FCK:editor
 *		id="EditorAccessibility"
 *		width="80%"
 *		height="120"
 *		toolbarSet="Accessibility"
 *	"&gt;This is another test. &lt;BR&gt;&lt;BR&gt;The "Second" row.&lt;/BR&gt;&lt;/FCK:editor"&gt;
 * </pre>
 *
 *<p>In this example we set all the attribute for the fckedit tag.
 *
 *<p>
 *  <b>Advanced usage of the tag</b>:
 *  <pre>
 *	&lt;FCK:editor id="EditorDefault" basePath="/FCKeditor/"
 *		styleNames=";Style 1;Style 2; Style 3" 
 *		fontNames=";Arial;Courier New;Times New Roman;Verdana" &gt;
 *		This is some &lt;B&gt;sample text&lt;/B&gt;.
 *	&lt;/FCK:editor&gt;
 *  </pre>
 *<p>In this example we set the id and the basePath of the editor (since it is /FCKeditor/
 * we could have omitted it because it's already the default value).<br>
 * Then we used the the optional attributes to set some advanced configuration settings.
