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.
