Make it easier to run tests in browser
Fix failing test
A few more regression tests
Set up mock responses for lazy loading tests
Can load data asynchronously
Add example
Add getItemsFromServer and getItemUrl
Clicking expand button fetches data
If in async mode, collapse folders by default
Test and refactor: implement addItemsFromServer
getItemUrl and getItemsFromServer take an item instead of UID
Can customize how item urls are built with the itemUrl options
Rename ajaxRoot -> ajaxSource
Don't lazy-load by default
