Tutorial demo: "Now you can submit..."

[runfish5]

• Under "Tutorial Demo": https://aribornstein.github.io/corefidemo/?demo=onboarding
  I assigned all three mentions. There is NO SUBMIT BUTTON !

• Under "Guided demo": https://aribornstein.github.io/corefidemo/?demo=guided
  I finished the first 'document 1' (Please review the sentence, it is a mistake in 'fearing arrest at home wanted them abroad.'). Upon starting document 2, I run into the error message:
  "The last word 'assign' should be a mention even though it wasn't provided as a candidate mention. Highlight abroad and press the n key then assign it to it's own cluster before continuing to the assigning the current mention."
  I tried highlighting 'abroad' + press n, but it didnt work.

• Under "Annotation Demo": https://aribornstein.github.io/corefidemo/?demo=annotation
  I just press shift until i reach following stats: Mention: 155/155 Document: 10 / 10 and then nothing happens.

I appreciate your efforts, I hope you can debugg it without much of an effort. I will now read the paper. 😄
