This PR adds
:pretty_print,:indentand:compactoptions to allow prettified XML output.There is an old PR #35 that has the same purpose, but it stumbled over problems in Builder gem. In this PR I don't mess with Builder gem but instead use
REXMLfrom standard Ruby library to format generated XML.Prettifying doesn't work for XML documents generated from an array without
unwrapoption set totrueas such documents are not valid and cannot be formatted byREXML. This case is just bypassed, no exceptions thrown.
