This is the first chunk of the work to construct an execution graph based on the intermediate representation in resourceInstanceObjects. For now this just constructs an independent subgraph for each resource instance object, without honoring any of the inter-object dependencies. A subsequent commit will add in all of those dependencies in an additional loop afterwards. Signed-off-by: Martin Atkins <mart@degeneration.co.uk>
