Modify initModelState to create ModelState_ls in memory. Modify getModelState to retrieve ModelState_ls from memory rather than file. Modify setModelState to change ModelState_ls in memory as well as to save model state file. Modify processModuleSpecs to call getModelState rather than readModelState. Modify simDataTransactions to fix bug so that simulation with datastore references work.
