cue-rs -- use CUE from Rust

This is a work in progress, expect constant churn and breakage.

Setup

Building cue-rs requires access to a statically-build libcue.

cargo build

If libcue is not installed system wide, specify its location like so:

BINDGEN_EXTRA_CLANG_ARGS="-I /path/to/libcue" LIBRARY_PATH=/path/to/libcue cargo build

cargo test

Similarly, pass BINDGEN_EXTRA_CLANG_ARGS and LIBRARY_PATH if needed.

TODO.

Please raise all issues in the main CUE repository, giving the title of the issue a cue-rs: prefix.
