Increased the ping rate and added functions

I have put the sleeptime at 0.3 so that the ping requests are monitored over a longer time period rather than in small bursts. That would ensure correct measurements.

Use an & after every function Call. It runs the function as a separate.

test facebook.com 300 &
test google.com 40 &
test 192.168.3.254 10 &
wait #waits for the above processes to complete

That's great..but I thought it'd be better if the tests run sequentially.. but nice trick.. wil be useful later on.
