room now sets headers on initialization

- moves sync.board.child call to variable definition because we aren't animals
Keep everything just as it was before Rao stepped away
- added header rows and columns to firebase
- started working on checking for completion at each connection
firebase no longer acts recursively

- child added listener switched to value, which does not act on children
- createBoardTransformation is now private to the closure
- check for completion loads headers
count now set to 100 for production
display Headers no longer talks to Randomizer
buildUserTable now corrects for no-locations edge case

this is a terrible commit message but I'm tired.
