IE support for web service data objects

[embeepea]

Multigraph's ability to fetch web service data, or csv data, from a non-same-origin server is currently broken in Internet Explorer (9 and older? not sure about IE 10). This is almost certainly due to the fact that the JQuery.ajax function does not correctly support CORS requests in IE, because (an oversimplified view) IE's handling of CORS is screwed up.

See

• http://www.html5rocks.com/en/tutorials/cors/ and
• http://bugs.jquery.com/ticket/8283 (see especially comment 43 near the end)

for more information. There is a JQuery plugin available that helps with the situation; see the above posts for details, and figure out how to incorporate that plugin into Multigraph, if possible.

A solution to this problem is included in the commit

in our ol-fcav project. Still need to work this into js-multigraph itself, though.
