Big Help File Update

I just put a lot of effort into adding more information in the Help file for users who want to customize their documents. It is now much easier to find out field name information for adding new fields to documents. Most of the field description screens in the Help file now also include the internal field names so that you know what you need to type into the Report Expression dialog. All of the Document Screen help sections how include extra information about the specific databases that are open and available for inclusion in custom documents. Let me know if you see other areas where I need to flesh out the Help files.
