Convert SpreaD3 files

The index.html file produced by SpreaD3 fails to load properly due to a CORS issue.

There's a Github issue that I (Terry) commented on here.

This repo holds the horrible shell script I wrote to convert the SpreaD3 output to something that works.

Usage

Here's (more or less) the message I wrote about it on the GitHub ticket:

The script will produce two new files, index-new.html and main-new.js. Open the former with your browser.

NOTE: this is extremely brittle. If the spread3 developers change what they write into main.js (which they certainly will do!), this code will cease to produce output that works. I've just written it so a colleague can work with spread3 and post it here in case it helps you. It also illustrates how the overall problem could be fixed, along the lines that I posted above.

If you don't see a map loaded in your browser, open the console and have a look for JavaScript errors. Then post them here & maybe I'll be able to help.

The person I wrote this for tells me he is using version 0.9.7.1 of SpreaD3. The above script is, I expect, highly unlikely to work on any other version.
