+The following code represents the burglar alarm Bayes network from
+Chapter 14 of Russell & Norvig, 2nd Edition.  This network representation
+is used in the corresponding Bayes net code found in this directory.
+
+The conditional probability tables consist of the values listed here
+(along with the probabilities of the corresponding complementary events):
+
+P(Burglary = true) = 0.001    (=> P(Burglary = false) = 0.999)
+P(Earthquake = true) = 0.002  (=> P(Earthquake = false) = 0.998)
+
+P(Alarm = true | Burglary = true, Earthquake = true) = 0.95
+P(Alarm = true | Burglary = true, Earthquake = false) = 0.94
+P(Alarm = true | Burglary = false, Earthquake = true) = 0.29
+P(Alarm = true | Burglary = false, Earthquake = false) = 0.001
+
+P(JohnCalls = true | Alarm = true) = 0.90
+P(JohnCalls = true | Alarm = false) = 0.05
+
+P(MaryCalls = true | Alarm = true) = 0.70
+P(MaryCalls = true | Alarm = false) = 0.01
