/**
	This class provides methods for asynchronous operations on files and
	directories. For synchronous operations, see `asys.FileSystem`.

	All methods here are asynchronous versions of the functions in
	`asys.FileSystem`. Please see them for a description of the arguments and
	use of each method.

	Any synchronous method that returns no value (`Void` return type) has an
	extra `callback:Callback<NoData>` argument.

	Any synchronous method that returns a value has an extra
	`callback:Callback<T>` argument, where `T` is the return type of the
	synchronous method.

	Errors are communicated through the callbacks or in some cases thrown
	immediately.
