mock more data

[rgbkrk]

Starting out with some mocks.

query randCell {
  randomCell {
    cellType:__typename
    ...codeCellGunk
    ...markdownCellGunk
  }
}

query randO {
  randomOutput {
    outputType:__typename
    ...streamGunk
    ...displayDataGunk
  }
}

fragment codeCellGunk on CodeCell {
  source
  metadata
  outputs {
    ...streamGunk
    ...displayDataGunk
  }
}

fragment markdownCellGunk on MarkdownCell {
  source
  metadata
}

fragment streamGunk on StreamOutput {
  name
  text
}

fragment displayDataGunk on DisplayData {
  data
  metadata
}

Something I think worth doing is setting up now.sh for this repo. I'll go ahead and do that.
