Pull in every source file in a directory as a module.

```toml
[dependencies]
automod = "1.0"
```

## Syntax

```rust
automod::dir!("path/to/directory");
```

This macro expands to one or more `mod` items, one for each source file in the
specified directory, excluding `mod.rs`, `lib.rs`, and `main.rs`.

The path is given relative to the directory containing Cargo.toml.

It is an error if the given directory contains no source files or if a file
name is not valid UTF-8.

The macro takes an optional visibility to apply on the generated modules:
`automod::dir!(pub "path/to/directory")`.

## Example

Suppose that we would like to keep a directory of regression tests for
individual numbered issues:

- tests/
  - regression/
    - issue1.rs
    - issue2.rs
    - ...
    - issue128.rs

We would like to be able to toss files in this directory and have them
automatically tested, without listing them in some explicit list of modules.
Automod solves this by adding *tests/regression.rs* containing:

```rust
mod regression {
    automod::dir!("tests/regression");
}
```

The macro invocation expands to:

```rust
mod issue1;
mod issue2;
/* ... */
mod issue128;
```
