Re: [Gpsbabel-code] Support for GPS loggers with MTK chip

[John D. <e4b...@ya...>]

Hello,
here is a second test version of the MTK-logger
support
for gpsbabel. Changes since last version:
 - a few bug fixes
 - less/no debug output unless you ask for it
 - internal CSV output uses gbfile api => you may
create
   a compressed file by naming it .gz
 - ...

Data downloaded from the GPS logger is still saved as
temporary
data.bin file. This may later be processed with the
mtk-bin interface. 

Example usage::
   # Read from USB port, output in GPX format
  ./gpsbabel -D 2 -t -w -i mtk -f /dev/ttyUSB0 -o gpx
-F out.gpx

   # Parse an existing .bin file
(data_2007_09_04.bin), output as
   #  both CSV file and GPX
  ./gpsbabel -D 2 -t -w -i
mtk-bin,csv=data__2007_09_04.csv -f
data_2007_09_04.bin -o gpx -F out.gpx

You may also add an 'erase' flag to the command which
will perform
an flash erase after downloading the GPS data.

  Todo:
    o Create a testsuit of .bin to .gpx/csv files, not
that original MTK application doesn't handle GPX.
    o More documentation ?
    o ....
