This is a very basic wrapper around the Rustyline crate that provides just 2 simple and easy to use functions. The function prompt(String), takes a string as a parameter to display as an input prompt and returns the keyboard input (sans the newline). The function edit_prompt(String, String) takes 2 parameters: the first, is just the prompt string, the second is an existing value you want to edit (be it a default or some other value) and returns any input.
That's it.
If you need more flexibility or features, just drop back to Rustyline. This library was just designed to save ~50 lines of code and make my source code cleaner on other projects.
