Make changes to toHtml output so that it supports an Edit form

The toHtml output for the x12 file needs some simple changes to make it easy to use in an application to support an online Edit form.

1. The id attribute of each loop/segment/element (which is a machine readable "path" to the x12 entity in the document) should include itself. Previously it only included it's parents, which was a bug.
2. Each loop/segment/element should have a title attribute containing a human readable "path" to the x12 entity.
3. For supporting multi-claim 837's, need a toHtml method that takes a data loop index.
4. And each data loop needs to be in a
   container with an ID to identify what data loop it belongs to. This allows a nice paging ability.
5. Add a class on the input text field for elements for each of css selectors

I have this work done but need to take some time to merge it. I may never get around to it but I'll try this or next month to make some time.
