+ Okay, so you want to build a SPModuleInput object.
+
+ This function first takes and does the build of the parent class,
+ which is SPModule. Then, it looks for the <input> section of the
+ XML description. Under there should be several fields which
+ describe the input 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.
