  == DESCRIPTION
  
  The `nng_http_handler_set_tree()` function causes the _handler_ to be
  matched if the Request URI sent by the client is a logical child of
  the path for _handler_.
  
  The `nng_http_handler_set_tree_exclusive()` function is similar to `nng_http_server_set_tree()`
  with the distinction that the _handler_ will be considered to *exclusively* handling its 
  Request URI. Other handlers will be tested against _handler_ when being added to a server, 
  possibly resulting in a URI conflict error.
  
  TIP: These methods are useful when constructing API handlers where a single
  service address (path) supports dynamically generated children.
