Allocate memory at compile time!

Currently, in stable rust there is no way to dynamically allocate or deallocate memory at compile time (i.e. in const fns). This crate allows you to do exactly that, in nightly rust, with the help of a few intrinsics and a lot of unstable features, so don't be surprised if it suddenly breaks, and please don't use it in production yet.

The crate exposes one type, ConstAlloc, which wraps any allocator and itself implements const Allocator. Using this type you can allocate and deallocate memory in const fns, which would theoretically also allow you to use something like Box<T> or Vec<T> in const contexts. Unfortunately, none of the relevant member functions on those types are const yet though, so unfortunately it's still not really possible (yet?) to use any standard library collection at compile time.
