  Session

SYNOPSIS: |

  Session::* offers a set of class for driving external progams via pipes.  It
  offers a significant abstraction over Open3::popen since stdout/stderr can
  be processed individually for each command.  Additionally the exit_status of
  each command is made available.  eg.

    bash = Session::Bash.new
    stdout, stderr = bash.execute 'ls'

  or

    bash = Session::Bash.new
    stdout, stderr = StringIO.new, StringIO.new

    bash.execute 'ls', :stdout => stdout, :stderr => stderr
    exit_sta
