[NEW] security/libnacl: Python bindings for NaCl
This library is used to gain direct access to the functions exposed by
Daniel J. Bernstein's nacl library via libsodium or tweetnacl. It has
been constructed to maintain extensive documentation on how to use nacl
as well as being tely portable. The file in libnacl/__init__.py can be
pulled out and placed directly in any project to give a single file
binding to all of nacl.
