interval join options to prefix field names from left and/or right tables #53

Closed alimanfoo closed 10 years ago

alimanfoo commented 10 years ago

For all kinds of two-table interval join, it would be useful to be able to specify a prefix to prepend to field names, for left and/or right tables. E.g., add kwarg options 'lprefix' and 'rprefix' which if not None will be used.

(Helps to avoid field name clashes.)
