Add starter app

[subfuzion]

Create a starter (barebones) MEAN stack app that can be used for a minimal verifiable deployment.

• [ ] Can be in an examples directory that a user can copy (easier, more expeditious for now)
• [ ] Can be in separate repo and referenced from the instructions here (maybe better for later)

random idea that just popped into my head, feel free to say no if it doesn't make sense, but would it make sense to combine this with the validation testing we want to do? My thinking is that, in terms of test scope, we really only want to be testing the deployment system. Writing a verification suite that's coupled to the existing demo app means we're testing the app as much as anything else.

Put another way, does it make for this starter app to provide both a template for people to build on top of, and a target for a validation suite?

again, I'm not sure if this is a good idea or making it too complicated or what, but I figured it was worth mentioning.
