Additional tests

[dtabell]

Add two more tests, to bring the total up too three. I'll look at the examples.

The goal here is to have a clear framework for adding tests in the future.

I'm capturing the TODO lists from the spinESRF_18GeV and spinSaturne tests here to

1. Exploit GitHub's issue progress bar and Markdown capabilities,
2. Eliminate the need for committing and tracking temporary TODO files, and
3. Gather all the TODO items related to this issue in one place.

spinESRF_18GeV To Do List

• Make sure we point to the correct zgoubi executable.
• Recheck the expected results after we update the various physical constants defined by zgoubi.
• Add color, etc, to output of test script.

spinSaturne To Do List

• Make sure we point to the correct zgoubi executable.
• Recheck the expected results after we update the various physical constants defined by zgoubi.
• Add color, etc, to output of test script.
• Fix X2 scale in the plot.

@dtabell I've checked off the items in the above comment's To Do lists to reflect the current status of the commits that I just merged into the add-zgoubi-tests branch. I'll need guidance from you to proceed on the unchecked boxes.

The work on this issue is ready for review.

@dtabell Let us know any of your thoughts upon reviewing the work on this issue. I'm not sure of the status of the unchecked boxes. If those are still requirements, I'll need further guidance on next steps.

Items remaining in the above ToDo lists are my responsibility.
