enable export to requirements notes

[hchiam]

Problem/Need:

The HTML export is fine for communicating with devs, but what about for non-devs to communicate with each other or just to remind themselves? Otherwise they'd just use something they're more familiar with, like excel files.

Suggestions:

• can https://github.com/jspreadsheet/ce export to excel?
  • if yes, then maybe it can be used to simply export
  • if no, can it be populated for use to copy-paste directly from browser cells into excel?
