@arthurpitman @mijdeed Please take a look and provide your feedback. Feel free to make changes to the template yourself.

Thanks!

I made some minor improvements to improve the readability.

We'll use the template too for modelio-cpswarm-modeler and modelio-attack-tree-module @kaischaabouni @etiennebrosse
