Java port of snappy, a fast compresser/decompresser written in c++, originally developed by google.

snappy's main target is very high-speed compression/decompression with reasonable compression size. so the compression ratio of snappy-java is modest and about the same as lzf (ranging 20%-100% according to the dataset).

this version of the java library is not the latest upstream version but it has an abi which is used by picard-tools package and was finally packaged exactly for the purpose to support picard-tools.
