Example of using the Facade Pattern.

The Facade pattern is used when a simplified version of an interface on a complicated sub-system is needed in situations where the whole complicated sub-system does not need to be exposed.

In this example, the complicated subsystem is a representation of a device network complete with scan chains, device idcodes, and device devices that can be selected and deselected. The Facade exposed by this complex network exposes only the scan chain, getting device idcodes based on an index into those scan chains, resetting the scan chains and selecting a device to appear in the scan chain.
