Title: Added support for memory taps that are empty

This is useful for testing scenarios with no tuples flowing through. It was supported in the Cascalog version of this a while back. This pull request prevents an ArrayIndexOutOfBoundsException that happens with the current version of maple.

Sending this pull request again to develop rather than master.
