+	 * <p>A comprehensive convenience class that bundles a context menu UI, 
+	 * the spelling engine, the dictionary loader, and user dictionary support 
+	 * to enable a single-line integration of spell checking functionality into 
+	 * any custom UI component built around TLF TextFlow.  </p>
+	 * 
+	 *
+	 * <p>For advanced text editing applications, more complex features are likely required.
+	 *	For those applications, we recommend bypassing this class and utilizing the <code>SpellChecker</code> class directly.</p>
+	 *
+	 * In order to display Squiggly custom right-click context menu, SpellUIForTLF extends TLF <code>ContainerController</code> class and overrides createContextMenu() method 
+	 * of <code>ContainerController</code>. This could have the following side-effects for a Squiggly client:
+	 * <ul>
+	 * 		<li>In case the Squiggly client application uses a derived controller that inherits from ContainerController class in order to show custom context menu items, Squiggly
+	 * 			context menu will override that. That essentially means that after SpellUIForTLF.enableSpelling() is called, client's own custom right-click menu items, if any, will not be
+	 * 			accessible. </li>
+	 * 		<li>Incase any ContainerController api needs to be called after SpellUIForTLF.enableSpelling() has been called, the client application will need to get the controller objects afresh 
+	 * 			from the TextFlow's FlowComposer. This is needed since SpellUIForTLF replaces ContainerController objects with new SquigglyCustomContainerController(derived from ContainerController) objects. </li> 
+	 * </ul>
+	 * 
+	 * 
+	 * <p><code>SpellUIForTLF</code> uses the AdobeSpellingConfig.xml file to lookup corresponding resource files for a given locale.
+	 * The default location of AdobeSpellingConfig.xml is [yourapplicationDirectory]/AdobeSpellingConfig.xml. This could be customized using 
+	 * <code>spellingConfigUrl</code> property of <code>SpellUI</code>. You don't have to change the content of this file. However,
+	 * if you want to add a new language, to use an alternative dictionary or to customize the location for your dictionaries, you can modify it. 
+	 * There's an known issue with IIS web server when loading dictionary files with unknown extensions, in which case you can modify the XML to work around it.</p><p>
+	 * A sample AdobeSpellingConfig.xml will look as follows:
+	 * <listing version="3.0">
+	 * <pre class="preWrapper">
+	 * &lt;?xml version=&quot;1.0&quot; encoding='UTF-8'?&gt;
+	 * &lt;SpellingConfig&gt;
+	 *   	&lt;LanguageResource language=&quot;English&quot; 	  languageCode=&quot;en_US&quot; ruleFile=&quot;dictionaries/en_US/en_US.aff&quot; dictionaryFile=&quot;dictionaries/en_US/en_US.dic&quot;/&gt;
+	 *    	&lt;LanguageResource language=&quot;Spanish&quot;    languageCode=&quot;es_ES&quot; ruleFile=&quot;dictionaries/es_ES/es_ES.aff&quot; dictionaryFile=&quot;dictionaries/es_ES/es_ES.dic&quot;/&gt;
+	 *   	&lt;LanguageResource language=&quot;Portuguese&quot; languageCode=&quot;pt_PT&quot; ruleFile=&quot;dictionaries/pt_PT/pt_PT.aff&quot; dictionaryFile=&quot;dictionaries/pt_PT/pt_PT.dic&quot;/&gt;
+	 *  	 &lt;LanguageResource language=&quot;Italian&quot; 	  languageCode=&quot;it_IT&quot; ruleFile=&quot;dictionaries/it_IT/it_IT.aff&quot; dictionaryFile=&quot;dictionaries/it_IT/it_IT.dic&quot;/&gt;
+	 * &lt;/SpellingConfig&gt;</pre>
+	 *
+	 * </listing>
+	 * Note: The languageCode can be an arbitrary value, as long as you are consistent when passing them to the Squiggly classes. 
+	 * However, we highly encourage you to follow the two part Unicode language identifier format. 
+	 * For more information, please consult the latest Unicode Technical Standard that can be found at: http://unicode.org/reports/tr35/.</p>
