    Hello Theodore, the semantics for Discrete Histogram is such that you have to specify
what classes or discrete values are going to arrive. Once you fix the allowed values, nothing
else can be added except for updating counts of the same values. 
    The idea is to emulate a discrete probability distribution, which it does. For the continuous
case, we're emulating a continuous probability distribution, which means we can effectively
add any value we want.
