Infrastructure for code formatting

This module defines [FormatElement], an IR to format code documents and provides a mean to print such a document to a string. Objects that know how to format themselves implement the [Format] trait.

Formatting Traits

• [Format]: Implemented by objects that can be formatted.
• [FormatRule]: Rule that knows how to format an object of another type. Necessary in the situation where it's necessary to implement [Format] on an object from another crate. This module defines the [FormatRefWithRule] and [FormatOwnedWithRule] structs to pass an item with its corresponding rule.
• [FormatWithRule] implemented by objects that know how to format another type. Useful for implementing some reusable formatting logic inside of this module if the type itself doesn't implement [Format]

Formatting Macros

This crate defines two macros to construct the IR. These are inspired by Rust's fmt macros

• format!: Formats a formatable object
• format_args!: Concatenates a sequence of Format objects.
• write!: Writes a sequence of formatable objects into an output buffer.
