@section intro Introduction
An Arduino sketch for testing the NMEA_EXTENSIONS to the library. Does
not require any GPS hardware. Boat is a data only object we can use to
represent the actual data and build sentences from. GPS is a data only
object that parses the sentences and saves the results, the same way you
would with a communicating GPS object
Only some of the data values will have added history. Note that history
is stored as integers, scaled and offset from the float values to save
memory. The AWA (Apparent Wind Angle) is recorded as three components,
so that sin and cos parts can be accurately time averaged. onList() allows
testing sentences against a list to see if they should be passed on to
another listener, allowing your sketch to act as an NMEA multiplexer.
Although it will just barely compile for an UNO with the NMEA_EXTENSIONS,
defining two GPS objects pushes the limits of the UNO data space and
should probably be avoided.
