This example models a fire-detection system.
It can be exercised as follows.

step 1) create an new database, e.g. called demo
 sh> monetdb create demo; monetdb release demo

step 2) initialize the datacell progream
 sh> mclient -d demo 
sql> \<emili.sql

step 3) in a different window sent events at a rate of 10/seconds

cat emilisensor.log |sensor --port=50500 --delay=100 --trace --replay
