A facade to OSWorkflow that gives us a place to cache workflow data as we need it while interacting with it. This class has kind of a strange interface due to the idiosyncracies of the OSWorkflow, particularly the Workflow interface. The idea is to encapsulate the interactions with OSWorkflow and eliminate the need to pass a Workflow reference and the workflow ID all over the place when extracting data from OSWorkflow
