+/**
+ * How to use the Runner:
+ * 
+ * create a resource, and fill out:
+ *   the context (supports the FHIRPathEngine)
+ *   a store that handles the output 
+ *   a tracker - if you want
+ *   
+ * Once it's created, you either run it as a batch, or in trickle mode
+ * 
+ *   (1) Batch Mode
+ *   
+ *    * provide a provider 
+ *    * call execute() with a ViewDefinition
+ *    * wait... (watch with an observer if you want to track progress)
+ *   
+ *   (2) Trickle Mode
+ *    * call 'prepare', and keep the WorkContext that's returned
+ *    * each time there's a resource to process, call processResource and pass in the workContext and the resource
+ *    * when done, call finish(WorkContext)
