Make it possible to chain regular functions.
By adding use pipe_trait::*, 3 methods are added to all types:
| identifier | pipe syntax | traditional syntax |
|:----------------:|:---------------:|:------------------:|
| Pipe::pipe | x.pipe(f) | f(x) |
| Pipe::pipe_ref | x.pipe_ref(f) | f(&x) |
| Pipe::pipe_mut | x.pipe_mut(f) | f(&mut x) |
