 * An intermediate representation of a DeploymentEntity which keeps track of all of the entity's ProcessDefinitionEntities and resources, and BPMN parses, models, and processes associated with each
 * ProcessDefinitionEntity - all produced by parsing the deployment.
 * 
 * The ProcessDefinitionEntities are expected to be "not fully set-up" - they may be inconsistent with the DeploymentEntity and/or the persisted versions, and if the deployment is new, they will not
 * yet be persisted.
