Comment about correct MatchedFilter usage.

Because the filter expects a combined translate/rotate and low-pass filter in the taps, the taps must be a multiple of the translate sinusoid period.

AIS decoding and really bad UI.
...
The decoder needs a serious refactoring/decoupling.
The UI just dumps bits of the received packets into a console window, whcih scrolls too quickly in an AIS-dense area with a good antenna.
