Okay, so you want to build a SPModuleOutput object.
This function first takes and does the build of the parent class,
which is SPModule. Then, it looks for the <output> section of the
XML description. Under there should be several fields which
describe the output module to excruciating detail. Those are parsed,
copied, and put into the structure that is passed in as module.
Overall, there are many levels of indentation, just to handle the
levels of indentation in the XML file.
