%description
Empowers users to fuzzily-merge data frames with millions or tens of
millions of rows in minutes with low memory usage.  The package uses the
locality sensitive hashing algorithms developed by Datar, Immorlica, Indyk
and Mirrokni (2004) <doi:10.1145/997817.997857>, and Broder (1998)
<doi:10.1109/SEQUEN.1997.666900> to avoid having to compare every pair of
records in each dataset, resulting in fuzzy-merges that finish in linear
time.
