I inherited this add-on code about a year ago when I took over the free 
software project, and got the feed code working, but didn't know enough 
to go about changing it, feared it might be too difficult, so I left it 
alone until it broke.

With a year of experience with this programming environment, I changed 
the feed reading from Atom to GeoJSON within a matter of seconds.  The 
process consisted of deleting all the convoluted XML DOM nested for 
loops, and doing a single for loop and direct assignment of only the 
properties I wanted.

Aside from 2 small errors in code due to typos, once corrected, 
everything worked as expected.  It was virtually effortless and 
painless.  The hardest part about the whole process was essentially to 
read the XMLHttpRequest docs and set `xhr.responseType = 'json';`, and 
then to look at `xhr.response` instead of xhr.responseXML.

Left it running for a few hours as a test.  Works just fine!
