nzscsingleplayertextinterface

A textual wrapper for nzscsingleplayer.

Starting with v0.5.0, nzsc_single_player::single_player_game::SinglePlayerNZSCGame no longer returns strings that the dependent application can use. Instead, it returns an nzsc_single_player::io::Output, leaving the details of how that Output object is displayed up to the dependent application.

Writing a command-line interface would now require much more code, because you now have to implement the stringifiers yourself.

This project is meant to be a drop-in solution for that.

It provides an easy way to convert nzsc_single_player::io::Outputs to strings (designed to be printed to a command-line):

```rust extern crate nzscsingleplayertextinterface; use nzscsingleplayertextinterface::{ question, notification };

let question: nzsc::io::Question = /.../; let notification: nzsc::io::Notification = /.../;

let s = question::tostring(&question); let s = notification::tostring(&notification); ```
