                  Pipe

Specialized pipe class for use by executeCommand.

The executeCommand function needs a specialized way of interacting with a pipe. First, executeCommand only reads from the pipe, and never writes to it. Second, executeCommand needs a way to discard all output written to stderr, as a means of simulating the shell 2>/dev/null construct.
