Overview

Because communication between the Agent/Service and TeamServer can only be initiated by outbound connections from the Agent/Service, we must provide a mechanism for the TeamServer to direct the Agent to take a specific action. This action is referred to as a Reaction. This class is how we handle those Reaction messages.
