Added code to noisey.  Currently using std::normal_distribution.  This seems like a good choice.  Need to test.  Currently passing in the subscribed signal data as the parameter for the distrubtion operator.  This should give a value maybe around the number?  My understanding may be off.  I may have to dynamically update the mean of the distribition and use it as a base for where the noise is going to be coming from.  This approach would make sense because then the generated noise added to the signal would be gaussian for sure.  All in all, need to keep playing.
