v0.2.0 - K2

Complete re-write to support multiple instances using a constructor function. In other words, more than one address form on the same page.

This changes invocation from:
contactDataServices.init(options);
to:
var address = new ContactDataServices.address(options);

Also, the following has been dropped:

• "Caching" - this was only happening on each page request
• Merge settings - the base object is now built up from the user's options
