26# Web interface.
27#
28# This module implements a thread that can perform (HTTP) requests
29# asynchronously. When the request is performed, a callback is called. The main
30# interface is the \ref Handler class. Each of its functions creates a \ref
31# Request subclass instance and puts it to the request queue. The handler
32# thread then takes the requests one by one, and executes them.
33#
34# This module also defines some data classes the contents of which are
35# retrieved or sent via HTTP. \ref BookedFlight contains data of a flight
36# booked on the MAVA website, \ref Fleet and \ref Plane represents the MAVA
37# fleet and the gates at Ferihegy and \ref NOTAM is a NOTAM.
