Issue37 navigator / Issue101 navigator follow-up / Issue102 navigator default

This pull has partial coverage of the topics raised in #101.

* Resize icon removed.
* Updated docs both on the navigatorId property and also on the Control object.
* The tests are faster (Although perhaps still not fast enough)
* Better test cleanup
* Navigator is off by default

The items that have not yet been done are, but per the request from @iangilman I am sending this along now.  I will keep working on these.

* An updated example
* The fix about the drag behavior

I also plan to look to see if there are further improvements I can make to the test speed.
