示例1: insertAction
/**
* This function allows a user to insert an Action button to the page.
* It accepts an `XMLElement` (which should be of the `Anchor` type),
* an optional parameter `$prepend`, which when `true` will add this
* action before any existing actions.
*
* @since Symphony 2.3
* @see core.Widget#Anchor
* @param XMLElement $action
* An Anchor element to add to the top of the page.
* @param boolean $append
* If true, this will add the `$action` after existing actions, otherwise
* it will be added before existing actions. By default this is `true`,
* which will add the `$action` after current actions.
