This is an extensive refactor of deferred_load.dart. The major changes are: * An 'EntityData' class to better model some of the polymorphism in the algorithm * An 'AlgorithmState' class to simplify updates. * An 'EntityDataCollector' to encapsulate collecting dependencies from 'EntityData' objects. NOTE: This patch may change output file numbering.
