Merge branch 'master' into dev
Delta BGs
  - Delta 35% font size, right of BG
  - BG font size reduced from 900% to 800% to fit existing d3.min.js formatting w/o errors
  - Delta formatted as +N, -N, +/-N
  - Retro works w/ strike-through
  - Delta colors do not follow BG trend (per Scott L.'s wip/iob-cob defaults)
    - 0+4 = grey delta
    - 5-9 = yellow delta
    - 10+ = red delta

TODO - Finalize HTML/CSS formatting of BG / Delta
TODO - Determine color behavior; independent of BG trend or follow BG trend?
