docs: Include specified library. - Depreciated. Now let's autoloading handle the file include.
  
  if a reference to the calling class is passed in, then the specified library
  will be invoked and a reference passed back to the calling class.
  
  If $exposeToView is set to true along with a reference to the calling class,
  then the library will be loaded into the calling controller's Data field
  for use within a View file.
