Execution Context

See https://github.com/dalet-oss/flex-jefexampleexecutor-service/tree/master/Service/src/main/java/com/ooyala/flex/jefexampleexecutor/actions/impl/assetcontext

Job execution requests contain two java maps (string and object) serialized with `jobContext` and `workflowContext` variables.

Enterprise

Enterprise carries out the following functions during execution:

• Fills in using the job and context variables upon launching a job.
• Updates the job and workflow context variables when JEF returns the job response.

Services

Plugin developers running executors can carry out the following:

• Receive job and workflow contexts:
  `String strAssetId1 = (String) jobContextVariables.get("asset");`
  `String strAssetId2 = (String) workflowContextVariables.get("asset");`
• Update the job and workflow context variables to send back the response:
  `jobResponse.setJobContextVariable("asset", “new value”);`
