/**
 * This class is a wrapper for the internal data structure of a Monitor. It adds info specific to this monitor 
 * too such as the details of the key.  However, it uses the data of the underlying monitor (such as hits/total/avg etc).
 * DecoMon stood for decorator though I suspec that this is no longer the decorator pattern.  It seems to be a useful
 * pattern of passing around hte internals and merging them with another classes differences though I am not sure what that
 * pattern is (similar to flyweight but with different intent).
