UniTable.compact fails on an empty table

[GoogleCodeExporter]

This was discovered with an older version of Augustus using numarray and python 
2.5.  It needs 
to be verified that it happens with a version based on numpy, but I expect that 
it is still an issue.

Pasted below is output from a UniTable that encountered this bug with.

>>> a
