check in rmx xml to tsv script
Merge pull request #2 from VertiPub/SA_xmldumper

The code assumes that all rows have the column order identical to that of header, which I suppose is true all the time. As an enhancement, it'll be nice if we capture the column order in header and check the order for each row. No need to do anything fancy if the order is broken; we can simply fail.

With this, if, for whatever reason, the order of columns differ we don't end up silently producing wrong output.
