Easy upload and annotation of new forms

[sdrp]

• Have an "upload new form" button on the left sidebar that lets users upload a scan/picture of a new form and annotate it with checkboxes/free response sections
• Can start by using Dan's "draw.html" (posted in Slack, needs to be re-discovered), which contains functionality to upload an image, draw rectangles on it, label the rectangles with names, and save the final product as an SVG (which contains the coordinates of the boxes in its file structure)

• The annotation process for each page is identical:
  • Step 1: User inputs name of form, and number of pages (ex. "Delivery", 2 pages)
  • Step 2: Equivalent of "Scan Record" where user clicks btw pages and select a file for each page
  • Step 3: User hits "Annotate files", and is brought to a page similar to our "Edit" page
  • Step 4: User sees the HTML/SVG representation of each page and can click btw them, add new questions, draw rectangles, etc.
  • Step 5: At the end of annotating all pages, the user can click "save", at which point the server saves all of the annotation data into a single JSON

@danielkunin and I made some good progress on this in the last two weeks. Moving it back to low priority for now as we focus on getting the upload + save steps of the pipeline polished for a project this summer.
