## Detailed Description

A wrapper around an input and an output stream.

SimpleIOStream creates an IOStream from an arbitrary InputStream and OutputStream. This allows any pair of input and output streams to be used with IOStream methods.

This is useful when you obtained an InputStream and an OutputStream by other means, for instance creating them with platform specific methods such as Gio::UnixInputStream::create(), and you want to take advantage of the methods provided by IOStream.
