+/**
+ * THead class
+ *
+ * This component is used to provide access to the <head> HTML
+ * element through prado code. You can access it via the
+ *
+ * <code>
+ $this->Page->Head
+ </code>
+ * property.
+ *
+ * The THead component provides functionality that is also available through
+ * the TPage component (it will remain in the TPage component for cases where a THead
+ * component is not included on the page), including:
+ *
+ * - <b>registerScriptFile</b>
+ * - <b>registerStyleFile</b>
+ *
+ * Additionally, there are additional methods
+ *
+ * - <b>registerScriptBlock</b>
+ * <br/>Register script to be output between <script> tags
+ * - <b>registerStyleBlock</b>
+ * <br/>Register script to be output between <style> tags
+ * - <b>registerMetaInfo</b>
+ * <br/>Register information to be output in a <meta> tag
+ *
+ * Namespace: System.Web.UI.WebControls
+ *
+ * Properties
+ * - <b>Title</b>, string, kept in viewstate
+ * <br/>Gets or sets the <title> of the page
+ *
+ * Examples
+ * - On a page template file, insert the following line to create a THead component,
+ * <code>
+ * <com:THead Title="My Prado Page"/>
+ * </code>
+ * The checkbox will show "Agree" text on its right side. If the user makes any change
+ * to the <b>Checked</b> state, the checkAgree() method of the page class will be invoked automatically.
