libeither 0.4.0

Either struct for Rust
Documentation
# libeither
An Either struct, that allows serialization to more formats (specifically TOML).

This library is heavily influenced by the [Either](https://docs.rs/either/latest) enum library.  If you don't need struct specific
serialization, you may want to use the enum Either instead.

## Features
* `serde` - Enable serialization (on by default)
* `unstable` - Enable unstable options (nightly only, off by default)
