Windows permissions

This crate provides safe Rust wrappers over several Windows permissions concepts, including:

• SID (Security Identifier)
• ACL (Access Control List)
• ACE (Access Control Entry)
• SD (Security Descriptor)

There are two kinds of abstractions:

• The primary Windows data structures are available and can be used directly.
• In the wrappers crate, there are safe versions of the Windows API functions. Any Windows API function not implemented should be reported as an issue.

Contributing

PRs are happily accepted! In general, unsafe code should be confined to the wrappers module -- the rest of this crate should be implemented in safe ways based on that code. Additionally, please include tests for any functionality you add.
