add boilerplate code for handling udp subscribers
add simple inline code for sending to udp remote
run the udp process inside a domain because socket.Send throws exceptions
update varname to camelcase
instead of wrapping in a domain, use the socket error event
rename 'dgram' to 'Dgram'
Merge pull request #79 from andyroyle/feature/add-udp-logging

Logging to UDP now works
