Looking at the Demo Adaptor
A good way to get a quick introduction to adaptors and adaptor development is by looking
at the demo adaptor that is included with the Image Acquisition Toolbox Adaptor Kit.
The demo adaptor is a functioning adaptor that does not require any hardware. You can
build the demo adaptor and run it to get familiar with how an adaptor works.
