--[[ Test of Expression Builder and Method Chainging DSL (Rules14)
     Lair Configuration DSL Case Study
     H. Conrad Cunningham, Professor

See the comments in the Semantic Model Module. 

This Lua module is based on Fowler's builder for the Expression
Builder and Method Chaining implementation of the Lair Configuration
DSL.

Developed for CSci 658, Software Language Engineering, Fall 2013

2013-10-15: Adapted from from rules14.rb

Note: I added trailing configuration call, assignment to "config", and
an explicit return from what was in the Ruby version.  This could be
added to to the header_code and trailer_code strings that are attached
to the DSL script before compilation.
