Create high level "device" objects out of the fine grained transforms and sensors

[joelkoz]

From a conversation in PR #261:

Create a bunch of high level class that is a collection of smaller classes auto-wired into the most common configurations. For example, create a new SmartSwitch class which has the entire Button->PressRepeater->ClickType->SmartSwitchController->LoadController->LEDLight->SKOutput chain defined in its enable(). We would in effect be wrapping the code in the examples into high level classes which would be must easier for the "junior programmers" to use.
