This class and open/close file descriptors with read/write/append access rights. Atomic append is supported on all platforms.

This class provides access to stdin, stdout and stderr of the VAST process. These are used within the <OsProcesses>
framework to provide redirection to VAST's stdio streams. Unlike normal file redirection, it ensures that the file descriptors handles are not closed as a result of process execution.

This class also provides cross-platform support for writing to NULL devices which will effectively discard output.
