This package defines filesystem APIs that can be implemented for different environments such as dart:io, Chrome Apps, or network filesystems.
The API includes FileSystem, File and Directory classes with interfaces
similar to those in dart:io, excluding synchronous operations and constructors.
All File and Directory implementations should not have public constructors,
and instances should only be retreived via a FileSystem instance. This ensures
that code that uses the interfaces defined here can work with any implementations.
