Contains a single static class with methods for manipulating filesystem paths.

Most of use are used to seeing:

$this->path = rtrim($path, '/').'/';

Problems arise when the path given is winbloze C:\foo\bar or for a stream wrapper vfs://foo

This package aims to provide commonly used methods for dealing with such paths.
