Import Neuroinformatics tutorial on converting Neuromorpho to OSB

[sanjayankur31]

https://github.com/NeuralEnsemble/NeuroinformaticsTutorial/blob/master/Exercises/Exercise1_NeuroMorpho_to_OSB.md needs to be imported to the docs. At the moment, we link to it.

The page needs to be checked for correctness also. For example, does the Java applet run? Does CVapp still work or is there a replacement?

Finally, what's the long term plan here (post OSBv1?)
