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 has "std" and "alloc" features that can be turned off
