Constant

A trivial comparator that returns a constant for any pair of strings or
sequences.

Implements functions for comparing strings, sequences and
numeric vectors for clustering and record linkage applications.
Supported comparison functions include: generalized edit distances
for comparing sequences/strings, Monge-Elkan similarity for fuzzy
comparison of token sets, and L-p distances for comparing numeric
vectors. Where possible, comparison functions are implemented in
C/C++ to ensure good performance.
