+// <Module><Scenario>
+//
+// i.e.
+//
+// ClassifyPendAuthorization
+//
+// <Module>
+// Classify - Function is an FWPS_CALLOUT_CLASSIFY_FN.
+// Perform - Function executes the desired scenario.
+// Prv - Function is a private helper to this module.
+// Trigger -
+// <Scenario>
+// PendAuthorization - Function demonstates pending authorization requests.
+//
+// Author:
+// Dusty Harper (DHarper)
+//
+// Private Functions:
+// PendAuthorizationWorkItemRoutine(),
