[ckan-discuss] Update Data API tutorial

[Rufus Pollock]

Hi All,

I've been working on a tutorial and documentation for CKAN / DataHub Data API:

<http://docs.ckan.org/en/latest/using-data-api.html>

Any feedback, especially based on usage, would be *very* welcome.

(You can also submit corrections or additions directly by hitting
"fork and edit" on the file here:
<https://github.com/okfn/ckan/blob/master/doc/using-data-api.rst>)

This tutorial complements general info on the DataStore here:

<http://docs.ckan.org/en/latest/datastore.html>
