Make sure REST endpoint works as expected

[steinmb]

We created a REST end point exposing the data as JSON structures allowing Tara to pull any data she needed to do her visualisations. To my knowledge she never used it.

For the data workshop there might be persons what want to hit machine-vision.no to generate its own data graph. Our exports are in flat csv format, but you they want to build a multidimensional graph of our data, this is one way of doing that.
