Holy grail of gradle use with the full power of groovy, is to have separate groovy classes in their own source files.

Previous attempts to use one (groovy) class in another have hitherto failed ( if the groovy classes were in separate source files ) when the (necessary) import statement in one class struck a "unable to resolve class" error

Therefore gradle settings file use of Groovy has been so far held back by being restricted to one enormous script file which clearly defeats good design and the benefits of OO etc

Here the Holy Grail (TM) is to demonstrate use of separate groovy source files and engage the groovy classes from within a gradle settings file
