Is it accessible?

[techieshark]

We might want to test for:

• blind users
• people who can't use mice
• colorblind people
• etc

Marking as question/help-wanted since I think the dept (IT?) has staff + resources that could help with this.

A lot of this was fixed by #200 and #204 See also: #240 and #336

Still to do:

• improving the map interface for blind users (#201)
• user testing
