Render a context type task handler given a list of handlers attached to a type.

Parameters

$task: The $task object in use.

$subtask: The id of the subtask in use.

$contexts: The context objects in use.

$args: The raw arguments behind the contexts.

$page: If TRUE then this renderer owns the page and can use theme('page') for no blocks; if false, output is returned regardless of any no blocks settings.

Return value

Either the output or NULL if there was output, FALSE if no handler accepted the task. If $page is FALSE then the $info block is returned instead.
