Recasting

This crate supplies the Recast and Recaster traits. These are currently intended for the translation of arena indexes like those in the triple_arena crate, however they can be used for any purpose of one-to-one recasting of values.

Currently, the traits need to be manually implemented, but there should be a macro in a future version that will automate implementation.

This crate is no-std by default, but there is a "std" feature for enabling certain impls.
