REPLAY Server
See source code in openburst/replay.
Target replay file
openBURST target replay files have to be provided in the folder openburst/replay/DATA
openBURST expects a python numpy target replay file of the following format:
DateTimeIndex, millisecs, converted_integer_id, lat, lon, heading[0 = north..180 = south..360 = north], speed[km / h], altitude[m], track_quality, milli_secs_after_midnight
sample content of such a replay file:

the following line in replayServer.py is hardcoded. The loop_time * X has to be changed for each computer (TBD how to generelize this)
remove_inactive_replay_targets((loop_time * 10)/replay_speed, now)
TODO:
replay seems to work using Tracks as ref file for the following config params in the browser client:
sampling time: 1s
replay update rate: 1s
ref track deletion time: 10s
test track delettion time: 10s
PROBLEM: when using a sampling time higher than replay update rate…the client air picture is empty —> so no speeded display of air picture possible
