[erlang-questions] Elevator demo

[Francesco Cesarini]

The Elevator example was implemented by Hakan Huss in the late 90s at 
Erlang Systems. It was part of the 5-day Erlang Literacy course aimed at 
test and support staff of the GPRS project. It has been used to 
demonstrate how Quick Check can test elevator systems, and featured in a 
few academic papers.
