Returns the named asset bundle.

This method will first look for the bundle in [[bundles]]. If not found,
it will treat `$name` as the class of the asset bundle and create a new instance of it.

@param string $name the class name of the asset bundle (without the leading backslash)
@param boolean $publish whether to publish the asset files in the asset bundle before it is returned.
If you set this false, you must manually call `AssetBundle::publish()` to publish the asset files.
@return AssetBundle the asset bundle instance
@throws InvalidConfigException if $name does not refer to a valid asset bundle
Returns the named asset bundle .
