I have a network stack

Please excuse the frivolity of this pull request. Without a public issue tracker, this was the only way I could send you a message.

I have written (for a class) a network stack in Rust, with the intention of adding it to an exokernel in Rust someday. You have the most actively-developed exokernel and, if the commit history is any indication, are currently adding networking support to it.

I would need to get permission from the Professor and my assignment partner to open source it, as it is a school assignment. But other than that I could start working on integrating the two in about a month, as that is when school gets out.
