Generates methods for working with tree view controls

 @example
   tree_view(:tree, :id => "treeId")
   # will generate 'tree', 'tree=', 'tree_items', 'expand_tree_item' and 'collapse_tree_item'
   # methods to get the tree value, set the tree value (index or string), get all of the
   # items, expand an item (index or string) and collapse an item (index or string)

 @param  [String]  the name used for the generated methods
 @param  [Hash]  locator for how the label is found
