/** Handles simulation output.
OUTPUT section definition
The following specifies the way that JSBSim writes out data.
NAME is the filename you want the output to go to
TYPE can be:
CSV Comma separated data. If a filename is supplied then the
data goes to that file. If "COUT" or "cout" is specified, the
data goes to stdout. If the filename is a null filename the
data goes to stdout, as well.
SOCKET Will eventually send data to a socket output, where NAME
would then be the IP address of the machine the data should
be sent to. DON'T USE THIS YET!
FLIGHTGEAR A socket is created for sending binary data packets to
an external instance of FlightGear for visuals. Parameters
defining the socket are given on the \
@code
@endcode
@code
@endcode
The arguments that can be supplied, currently, are:
RATE_IN_HZ An integer rate in times-per-second that the data is output. This
value may not be *exactly* what you want, due to the dependence
on dt, the cycle rate for the FDM.
The following parameters tell which subsystems of data to output:
simulation ON|OFF
atmosphere ON|OFF
massprops ON|OFF
aerosurfaces ON|OFF
rates ON|OFF
velocities ON|OFF
forces ON|OFF
moments ON|OFF
position ON|OFF
coefficients ON|OFF
ground_reactions ON|OFF
fcs ON|OFF
propulsion ON|OFF
NOTE that Time is always output with the data.
The class FGOutput is the manager of the outputs requested by the user. It
manages a list of instances derived from the abstract class FGOutputType.
