This library provides wrapper types that permit sending non Send types to other
threads and use runtime checks to ensure safety.

## Example

```rust
use std::thread;

// creating and using a fragile object in the same thread works
let val = Fragile::new(true);
assert_eq!(*val.get(), true);
assert!(val.try_get().is_ok());

// once send to another thread it stops working
thread::spawn(move || {
    assert!(val.try_get().is_err());
}).join()
    .unwrap();
```
