<!-- Proof of concept of running loleaflet.html in an iframe.
The top part of this page has a form with three input fields:
"x", "y", and "color", a submit button, and a "result" field used
for output only.
When the submit button is pressed, the input fields are passed as
a postMessage to the iframe. The message also specifies what
Python script to call. (In this demo case, the 'SetCellColor'
script in scripting/examples/python/SetCellColor.py in
LibreOffice core.) The parameters are then in our JavaScript
passed on to the Python script that acts on the document open in
the iframe. The Python script returns a value, which gets passed
to loleaflet in a unocommandresult: message, and passed on to the
event listener on this page, which writes it to the output field.
