Crate with_dir

Structs

• WithDir
  Scoped modifier of the current working directory. This uses RAII to set the current working directory back to what it was when the instance is dropped. This struct uses a static parking_lot::ReentrantMutex to prevent WithDir on other threads from updating the current working directory while any WithDir instances exist. However there is nothing stopping other threads from calling std::env::set_current_dir directly which would override the working directory.
