<!--
  README:
  This is the code that should be C&P into the edX UI for a problem.
  Add a new component called "problem"
  Select the problem type "Blank Advanced Problem"
  Edit the settings to give the problem a reasonable name.
  Paste this entire file in the text box.

  When using this file, you need to set:
  html_file='' to the proper HTML file path. It should start with '/static'

  If you have a starter file:
     set initial_state='' to 'starter file',
     otherwise it should be 'no starter file'.
