TreeView component readme doc :: issues

[abumami]

The readme doc for the Treeview component doesn't conform to the readme docs of other components.

• element names in the elements diagram do not match the names in the "Subcomponents (pseudo-elements)" table
• need a "better" elements diagram that more clearly identifies the elements using the "correct" element names
• props aren't quite "standard" (that is, they aren't described as in other components)
  • React.EventHandler (other components use "function")
  • React.ComponentType (other components use a more "specific" type)
• Is the "Custom CSS States (pseudo-classes)" list complete? Are they "custom" states or standard?
  • what about :error and "standard" states?
