This package provides the base class resources used in the creation of cajo services and controllers. Normally application specific classes would not be added to this package. It also contains the Client class, used by remote clients, to view the service's user interface, if it supports one.

NB: It is also very simply possible to create a Client application of your own, that lays out controller views from multiple services. This was not included in the sdk for both brevity, and since most applications of a multiple view frame are typically highly application specific.
