This crate is an augmentation of the `proptest::proptest!` macro to work with `async` tests.
```rust
proptest_async::proptest! {
}
```
The macro currently hardcodes `async_std` as the executor. Could be easily converted to work with
Tokio (e.g. using a feature switch), but I haven't gotten around to this.
I'll probably eventually clean it up and upstream to the proptest project.
