Summary: Upgraded from ant tree library to the much more capable React complex tree. Added the following: 1. Ability to expand / collapse nodes while automatically expanding / collapsing active/inactive children when they change 2. Keyboard controls of tree all the time 3. Basic search functionality 4. Selecting node in tree focuses and scrolls in the tree 5. Hover state for tree Reviewed By: lblasa Differential Revision: D40633876 fbshipit-source-id: 8dcef5ec2c277e476a3eb3cdaef62b15c25323c0
