A rust crate for simple path (like PATH and LD_PATH) use.
Other crates can create a simpath that loads from the path defined as an environment variable using:
let path = simppath::new("LD_PATH");
let file = path.find("filename");
##Methods Methods exist to find a file on the path as a PathBuf or as a URL with the "file:" scheme.
The path can be extended with additional directories to search in, but this won't affect the value of the environment variable that was loaded initially.
