A wrapper for the `fmt::Write` objects that efficiently appends indentation
after every newline.

This type is intended primarily for writing error reporters that gracefully
format error messages that span multiple lines.

## Setup

Add this to your `Cargo.toml`:

```toml
[dependencies]
indenter = "0.2"
```

## Example

```rust
use std::error::Error;
use std::fmt::{self, Write};
use indenter::indented;

struct ErrorReporter<'a>(&'a dyn Error);

impl fmt::Debug for ErrorReporter<'_> {
    fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result {
        let mut source = Some(self.0);
        let mut i = 0;

        while let Some(error) = source {
            writeln!(f)?;
            write!(indented(f).ind(i), "{}", error)?;

            source = error.source();
            i += 1;
        }

        Ok(())
    }
}
```
