Crate alloc_compose

Composable allocator structures for plugging together more powerful allocators.

alloc-compose relies on AllocRef as allocator trait. Until AllocRef has been stabilized, this crate requires a nightly compiler.

The design of composable allocators is inspired by std::allocator Is to Allocation what std::vector Is to Vexation by Andrei Alexandrescu and the Phobos Standard Library of the D Programming Language.
