[Bldg-sim] EnergyPlus Node Structure/Diagram

[Justin Spencer]

I can't overstate the usefulness of drawing yourself a big diagram of your
HVAC loops, with your nodes and each component labeled.  This is an area
that would benefit so much from a quality graphical user interface.  When
working in idf, you really need to draw your HVAC diagram to have a prayer
of success with a complicated system.  Debugging hvac loops in EnergyPlus is
really hard to do.
