* sparsehash: initial release:
The sparsehash package contains several hash-map implementations,
similar in API to SGI's hash_map class, but with different
performance characteristics. sparse_hash_map uses very little
space overhead: 1-2 bits per entry. dense_hash_map is typically
faster than the default SGI STL implementation. This package
also includes hash-set analogues of these classes.
