[flow-tools] AS info from V05 files

make sure you have this in your router config to ensure that AS 
information is handy.

ip flow-export version 5 origin-as
ip flow-export 10.0.0.1 9990

you can therefore view the AS information with:

flow-cat -p <data directory> | flow-print -f4

or:

flow-cat -p <data directory> | flow-stat -f19 (or -f20 and -f21)

btw, i suggest you read the INSTALL file because the example there
stores AS information and uses v5 netflow flows. also don't forget
to check out the man pages for flow-print and flow-stat. you can
also use the flow-report tool.
