yes, I like the idea of using .ini type file format or XML, very much.
There are parser available which will automatically building python
objects from this, won't they (like configparser)? I'll have to get
reading over the weekend...

ok, so it actually returns the class object itself.
One thing that confuses me is that objects have a name (self.name) but
object instances also have a name (e.g. myspecialturbine = turbine(...)
---- how do I discover the name 'myspecialturbine' ?). And object
instances have a class name too ('turbine'). Aaargh, too many names!
what if just want to know what the name of the instance is (in this
case 'myspecialturbine'?)
Right. I'll have a go at pulling all this together over the weekend
hopefully. Hurrah! Thanks for all the help, to everyone.
