[aprssig] APRS Network Analysis

[Andy Pritchard]

Hi All

I have put together a quick UI-View32 addon to analyse the paths used on the 
APRS network and plot the analysis on UI-View32

What is interesting about the analysis is that the sample showed that in 
Europe [WIDE1-1,WIDEn-n] is used in 892 paths whilst [RELAY, TRACEn-n] is 
used in 429 paths.

What is most concerning about this is in Europe most digipeaters do not 
implement UITRACE on the WIDEn-n (it's on TRACEn-n)

Because of this we need to inform our users to stop using WIDE and WIDEn-n 
in there paths and to make use of the default TRACEn-n functionality built 
into our European APRS network
