+ * The following config object properties are supported:
+ * <pre>
+Property Type Description
+---------- --------------- ------------------------------------------------------------------------------------
+animEl String/Element An id or Element from which the message box should animate as it opens and
+ closes (defaults to undefined)
+buttons Object/Boolean A button config object (e.g., Roo.MessageBox.OKCANCEL or {ok:'Foo',
+ cancel:'Bar'}), or false to not show any buttons (defaults to false)
+closable Boolean False to hide the top-right close button (defaults to true). Note that
+ progress and wait dialogs will ignore this property and always hide the
+ close button as they can only be closed programmatically.
+cls String A custom CSS class to apply to the message box element
+defaultTextHeight Number The default height in pixels of the message box's multiline textarea if
+ displayed (defaults to 75)
+fn Function A callback function to execute after closing the dialog. The arguments to the
+ function will be btn (the name of the button that was clicked, if applicable,
+ e.g. "ok"), and text (the value of the active text field, if applicable).
+ Progress and wait dialogs will ignore this option since they do not respond to
+ user actions and can only be closed programmatically, so any required function
+ should be called by the same code after it closes the dialog.
+icon String A CSS class that provides a background image to be used as an icon for
+ the dialog (e.g., Roo.MessageBox.WARNING or 'custom-class', defaults to '')
+maxWidth Number The maximum width in pixels of the message box (defaults to 600)
+minWidth Number The minimum width in pixels of the message box (defaults to 100)
+modal Boolean False to allow user interaction with the page while the message box is
+ displayed (defaults to true)
+msg String A string that will replace the existing message box body text (defaults
+ to the XHTML-compliant non-breaking space character ' ')
+multiline Boolean True to prompt the user to enter multi-line text (defaults to false)
+progress Boolean True to display a progress bar (defaults to false)
+progressText String The text to display inside the progress bar if progress = true (defaults to '')
+prompt Boolean True to prompt the user to enter single-line text (defaults to false)
+proxyDrag Boolean True to display a lightweight proxy while dragging (defaults to false)
+title String The title text
+value String The string value to set into the active textbox element if displayed
+wait Boolean True to display a progress bar (defaults to false)
+width Number The width of the dialog in pixels
+</pre>

+ * Example usage:
+ * <pre><code>

+ title: 'Address',
