30# Web interface.
31#
32# This module implements a thread that can perform (HTTP) requests
33# asynchronously. When the request is performed, a callback is called. The main
34# interface is the \ref Handler class. Each of its functions creates a \ref
35# Request subclass instance and puts it to the request queue. The handler
36# thread then takes the requests one by one, and executes them.
37#
38# This module also defines some data classes the contents of which are
39# retrieved or sent via HTTP. \ref Fleet and \ref Plane represents the MAVA
40# fleet and the gates at Ferihegy and \ref NOTAM is a NOTAM.
