PID files are a crude form of locking which uses the filesystem to ensure that only one instance of a
program is running at a time. This crate provides a simple API for creating and managing PID files
in a way that is safe and easy to use. PID Files will be cleaned up on drop, and can be checked for
existence and validity.

There is already a [pidfile](https://crates.io/crates/pidfile) crate, but it is not updated. This one
is a more modern approach to the same problem, and on crates.io as `pidfile2`.
