I think it should be the job of the layer to retrieve data for a given location (instead of the control). The first part of this change creates a `getData` method on the layer and updates the control to use this method. The second part of this change removes the assumption that the data returned will be an simple object representing feature attributes. The UTFGrid specification doesn't say anything about the structure of property values in the optional data member. The examples given in the spec use string values. The default callback previously assumed that the data could be rendered in a two column table. I think it would make more sense not to make this assumption. With this change, the user must always provide a callback to do anything with returned data.

Getting OpenLayers
OpenLayers lives at http://www.openlayers.org/. Find details on downloading stable releases or the development version the development site
Installing OpenLayers
You can use OpenLayers as-is by copying build/OpenLayers.js and the entire theme/ and img/ directories up to your webserver and putting them in the same directory. The files can be in subdirectories on your website, or right in the root of the site, as in these examples. To include the OpenLayers library in your web page from the root of the site, use:
<script type="text/javascript" src="/OpenLayers.js" />
As an example, using bash (with the release files in ~/openlayers):
$ cd /var/www/html
$ cp ~/openlayers/OpenLayers.js ./
$ cp -R ~/openlayers/theme ./
$ cp -R ~/openlayers/img ./
If you want to use the multiple-file version of OpenLayers (for, say, debugging or development purposes), copy the lib/ directory up to your webserver in the same directory you put the img/ folder. Then add the following to your web page instead:
<script type="text/javascript" src="/lib/OpenLayers.js" />
As an example, using bash (with the release files in ~/openlayers):
$ cd /var/www/html
$ cp -R ~/openlayers/lib ./
$ cp -R ~/openlayers/theme ./
$ cp -R ~/openlayers/img ./
Using OpenLayers in Your Own Website
The examples directory is full of useful examples.
Documentation is available at http://trac.osgeo.org/openlayers/wiki/Documentation. You can generate the API documentation with http://www.naturaldocs.org/: As an example, using bash (with the release files in ~/openlayers):
$ cd ~/openlayers/
$ /path/to/NaturalDocs -i lib/ -o HTML doc/ -p doc_config/ -s Default OL
Information on changes in the API is available in release notes found in the notes folder.
