 Caboose is a demand driven chain of processes. 
 a <- b <- c 
 a -> c -> c 
 a is a caboose, b is a car, c is an engine 
 requests for data flow from engine to caboose 
 data flows from caboose to engine 
 all a, b and c have a tank that holds outputs 
 all a, b and c have a data list that hold inputs  
 all a, b and c have a function 
 but the function is not applied in a caboose 
 the function turns inputs into outputs
