1. With reference to challenge 1, eliminate a specific event
if the average quantity (the arithmetic mean) for that event is above 1.05.
Hint: ungroup.
	homefin_1.q

2. Compute the online NAV of a set of portfolios
and when the NAV falls below a certain value (given as a command
line value), send an alarm  message to a remote site that should print 
out a message.
Processing should continue. So for our example data, the following
two processes 
	q homefin_2remote.q
	q homefin_2source.q 300

should cause the following to print out:

"Bad news! NAV has fallen to 90"
"Bad news! NAV has fallen to 110"
"Bad news! NAV has fallen to 110"
"Bad news! NAV has fallen to 230"
"Bad news! NAV has fallen to 250"
"Bad news! NAV has fallen to 290"
