read_sms_mesh bug fix and enhancements
First commit here is a bug fix for the case where both xy and lon/lat coordinates are available, and lon/lat was being overwritten with zeros. Note that this partially reverses a change that you made in Sept 2015 (commit 4bbe89d7). I'm pretty sure this is simply an edge case that you didn't think of then, but I'm highlighting it here in case it was intended behaviour.
Then, a couple of improvements that I've had queued up for "once the repo was sorted out".
