A Normalizer specifies a function to normalize arbitrary distance values
between 0 and infinity to the realm of 0 to 1.
In that respect a Normalizer is similar to the notion of a (sigmoid)
squashing function. Only that we need just the "right half" of the squashing
function, namely the mapping of the interval [0, infinity) to [0, 1]. This is
required to fulfil a normalization constraint for the Comparator interface,
such that dissimilarities are about equally scaled.
Please refer to the Comparator interface for more information.
