using names before they're defined

Bruno,

Thanks. An issue is that I need to be able to link multiple objects to
a single object etc.
Say for example using the previous wording, I might have compressor -
multiple combustors - turbine

this complicates things slightly.

my current thought is to do a two stage initialisation

1. create the objects
compressor = compressor()
combuster1 = combuster()
combuster2 = combuster()

etc

2. link them
compressor.link(downstream = [combuster1, combuster2])
combuster1.link(upstream = compressor)
etc.

hmmmm I need to give it some more though, particularly how I solve all
the linked objects (which is the point)

Dave
