Add explanatory/informational text

[kaijagahm]

Explain:

• What are these sentences/how were they chosen?
• Background information about the YGDP
• Maybe a separate tab with an FAQ section? [may need a separate dashboard or tab layout for this]

Thinking of removing the social vars tab for now, since I don't think I'm going to get around to making those graphs. That tab can be an informational tab.

Use the "How to use" tab in SCOSYA for inspiration

Have separate sections for points vs. interpolation mode.

Note that you have to click "apply" to propagate your changes.

Discuss how decisions were made, e.g. about gender/race categories.

Make a note of the Alaska limitation.

Could have the text just appear in the main body of the app. Not ideal (would be better to have it open a collapsible tab over the map itself), but I don't know how to do otherwise. Maybe someone else can figure out a better way.

Added some of this info to the About and How To tabs, though I didn't add everything yet.
