Data Filter Menu Design: edit preset narrative subtext design and content

https://github.com/codeforboston/mattapan-mapping/issues/126 provides the preset narrative text.

For the subtext design, determine where subtext shows. For example:
- Does the subtext show inside the preset narrative text button so that it shows "Land Use/Housing: What's going on with housing/How is land used in Mattapan?" inside the button?
- In the above example, will clicking on Land Use/Housing button then go to another set of buttons with subquestions, similar to what's displayed for preset narratives (two in above example) : 1.) What's going on with housing? 2.) How is land used in Mattapan?
- Will clicking on preset narrative button go to data filter menu? And then will subtext show above the data filter menu with the check off boxes? If so, is it just text, or will there be some button to display correct data filters/checked data filter boxes?

When subtext context has been finalized for each preset narrative text, they can be listed here.
