Hello AtomicTNode

AtomicTNodes intro - what they are, what they do.

Walk through the tutorial using an open-source demo strategy for what we call a simple resistive hydronic heating system. This code emakes some simplifying assumptions that one would want to adjust for better performance in the field, but captures many of the core functional concepts of an AtomicTNode operating for a thermal storage asset that is indeed an appropriate part of the mix for a high renewables future.
