Fixed bug in parsing the title from the response in Entity.cik(). There are multiple 'title' tags in the response, and the previous parsing was order-dependent. Now, by searching for a title tag at the top level, the parsing will work regardless of the order of the elements.
Merge pull request #2 from jimlindstrom/FixBugInEntityCik

Looks like the xml schema might have changed. Thanks for finding and debugging. Will merge, bump and push a new version.
