gp_map option to separate data file

[layik]

Update, this is not "straightforward" and requires removing the jsx pattern of writing the JS code which is preferred in my coding style. It may need a rewrite of the current "standalone" template file.

at least

So I have found the way to do this.

The only way to do this, is to have a precompiled version of the code in ES as stated by the React docs, and import into the browser with a standard <script src='react_no_jsx.js'>. I would like to keep my code in JSX and there is a good reason for it (human readability and conciseness). In our case a 251 line is transpired into 325.

But providing docs for this would mean a considerable amount of work. Example section below.

To clarify:

1. keep html code & scripts in a file say geoplumber.html
2. keep React code in a file say react.js (as in the example above)
3. data in data.json (or data.js)

But I see little value in the whole exercise I must say.

This is not useful even if done. Revisit if need be.
