Table Data : allow infinity and undefined #14

It would seem to be useful to allow for infinity or undefined in numeric
data.  This could be particularly useful for handling divide-by-zero or
network distance calculations.  For the network distance calculation, we
could possibly avoid infinity by disallowing certain calculations on
disconnected graphs.

Update Mar 5, 2013: As of 1.2 we do handle undefined.  Due to limitation in 
DBF, it is not possible to distinguish between infinity and undefined.
