Resolve "run examples in ci as integration tests, preferably with assertions"

Closes #51 (closed)

@christian_eichenberger : This looks great ! We just have to be careful to not include any heavy examples from the examples folder in the CI. I suspect there would soon be examples which involve full blown training, and those would just hog onto the CI resources. We can have a simple exclusion scheme which can be used to exclude certain examples if necessary.

@mohanty Thanks for your comment. I agree. And it should not mislead us into not increasing test coverage.
