note top : a node is a component in a link object,\n represented by its ID
argo -> argo
note bottom : We want to prepare the list of branches by removing\n nodes that appears several times\ne.g : two branches :\n1 - 2 2 - 3 3 - 4\n1 - 2 2 - 3 3 - 5\nWe will iterate over each branch to create the component's YAML\n and don't want to create components 1 2 et 3 twice or more
