When exporting a lattice geometry to XML without the lower_left specified, an error is thrown that is hard to debug. I localized this in the code and threw a helpful error so that a user is less frustrated when this happens.
ValueError: Lattice 1 <lower_left> has not been specified.
Description
When exporting a lattice geometry to XML without the lower_left specified, an error is thrown that is hard to debug. I localized this in the code and threw a helpful error so that a user is less frustrated when this happens.

Fixes #2902
