Added maybench, an automated benchmarking tool. The tool depends on benchpress,

a Haskell library for timed command execution.

For starters, the expression lives in development/libraries/haskell/maybench.
It doesn't really belong there because, though, because, technically, it's an
executable, not a library. If someone has a better idea, please feel free to
move it.
