This library provides wrapper types that permit sending non Send types to other

threads and use runtime checks to ensure safety.

It provides the `Fragile`, `Sticky` and `SemiSticky` types which are

similar in nature but have different behaviors with regards to how destructors

are executed.  The `Fragile` will panic if the destructor is called in another

thread, `Sticky` will temporarily leak the object until the thread shuts down.

`SemiSticky` is a compromise of the two.  It behaves like `Sticky` but it

avoids the use of thread local storage if the type does not need `Drop`.

## 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();

```
