QuestionnaireResponse narrative generation

[liambarnes]

Describe the bug

1. Nested repeat groups are not supporting in narrative.
   QuestionnaireResponse.text.div does not provide the right information and therefore the preview screen also does not display correct info (see image)

2. Narrative also does not include units for decimal/integer types (see image). Units are not included in the QuestionnaireResponse as these are not answer values. They are defined in the Questionnaire and are what the renderer use to display the correct units.

3. Narrative uses non-conformant HTML elements for XHTML

To Reproduce

1. Launch GPCCMP with context
2. Open previous response - I've saved a draft QuestionnaireResponse demonstrating this (also attached)

QuestionnaireResponse-974.json

Expected behavior

1. text.div and narrative display should contain the data in the structured QuestionnaireResponse and provide the user with a usable view even when nested repeat groups.
2. text.div and narrative display should contain any relevant units as displayed in the rendered form.
3. Only XHTML elements are used.

I think it is working now , but before proceeding to do a pull request, wanting to confirm the output is okay?

The Problem/Needs , Interventions and actions and Services and treatments are coming up as columns. Is this something we want to change in the Questionnaire? See image:

The issue is the indiscriminate use of tables for group items. While it tends to work well for a group that has single answer items directly below it, it doesn't account for more complex structures. "Problems/Needs" is a single repeating item that sits below a "Goals and tasks" group item. As siblings to "Problems/Needs" there are further group items. The narrative generator needs to be able to deal with this and not stick them all in a single table. Having a table continue horizontally to fit all descendent items in it is not going to provide a print friendly format.
