Tracks
Tracks are the most implicit thing in Mélodium. When models are instancied and treatments connected together, it creates a potential track. The track is the whole ensemble of treatments and flows between them, that are created together, live together, and disappear together.
A track always takes its origin from a model, who request its initialization when needed and as many times as needed, for each file found, each incoming connection, or whatever the model purpose proposes. Each of them will follow the same defined chain of treatments, but on their own. This is one of the core element providing Mélodium its strong scalability.
