libnnpack

This is a Rust binding to NNPACK (https://github.com/Maratyszcza/NNPACK).

Most of the NNPACK functionality is provided as FFI bindings, but convenience interfaces are provided for lazy context creation (NnpackHandle) and thread pool reuse (NnpackPthreadPool).

The build script should compile NNPACK from sources. Building assumes that the following commands are available on the system:

• virtualenv
• python2.7
• gcc-4.9 and g++-4.9
