+    This class acts to replicate sensor information with the network to come to a consensus
+    of an activity occurrance. This is based upon research by Song et al. available at:
+    https://ieeexplore.ieee.org/document/5484586
+
+    The main advantage of this approach, as apposed to techniques such as by using zookeeper
+    or consul, is it can be completely decentralised and so works without a central server,
+    or needing to elect a central server. Additionally, it does not require all nodes
+    to run a Zookeeper/Consul server instance, which were not designed for these constrained
+    combat environments, which will fail if half the nodes fail, and also use a lot of resources
+    for handling services not required by this task. 
+
+    The original approach in the paper requires some previous training before sensing, so 
+    that there is a probability of a given action based upon the previous set of actions.
