HALs, as they are called, are interfaces which are then implemented by drivers that enable that functionality. HALs allow for operating systems to easily be ported to different systems because the machine specific implementations for the operating systems are cordened off from the main operating system behind these HALs.  Behave-graph takes this same approach.

 Example abstractions in behave-graph:
 
-* ILogger.  The logging interface allows for behave-graph to report verbose, info, warning and error text messages.  The command line graph-exec tool uses the driver DefaultLogger to output these messages to the console.
-* ILifecycleEventEmitter.  This interface is responsible for emitting when the behave-graph should start, tick and stop.
-* IScene.  This interface is responsible for doing basic scene manipulations.  In the three example, this interface is implemented by the ThreeScene class that maps these operations to a Three.js-based scene graph.
