Detailed Description
Base class for all Apps.
The idea is that you can have multiple Apps in your program. Each App has three funtions:
setup() is called to let the App load all needed resources
runToCompletion() is called and will not return until the App exits
teardown() is called to let the App free allocated resources
For an example of Apps in use, see the AppLauncher class
Definition at line 32 of file App.h.
