Purpose: WriteSentry encapsulates the way an output file is written
to. It also provides a convenient way to open, write to, and close
a file, merely by declaring a WriteSentry object in a given Python
scope. When the WriteSentry object goes out of scope, the __del__
method is called, and the file is flushed and closed.
