[Closes #146] Simulation/Prediction Ending Strategy

[teubert]

Add a method of specifying a "strategy" for ending simulation and prediction. This is called the "event_strategy", and can be one of the following:
'first': Stop when the first event of the list is met
'all': Stop when all events in the list are met

Also added tests and added to tutorial.

Note: UTP is setup to only support 'all'. If you specify anything else, it will return an error. #150 opened to eventually add this functionality

Thank you for opening this PR. Each PR into dev requires a code review. For the code review, look at the following:

• Reviewer (someone other than author) should look for bugs, efficiency, readability, testing, and coverage in examples (if relevant).
• Ensure that each PR adding a new feature should include a test verifying that feature.
• All errors from static analysis must be resolved.
• Review the test coverage reports (if there is a change) - will be added as comment on PR if there is a change
• Review the software benchmarking results (if there is a change) - will be added as comment on PR
• Any added dependencies are included in requirements.txt, setup.py, and dev_guide.rst (this document)
• All warnings from static analysis must be reviewed and resolved - if deemed appropriate.

I ran with the SWS model and the shell script driving prog_server. Looks to be working. Thanks for the feature!
