Sequence Diagrams
The entry point to a cohorte session is the validation of a TopComposer component.
The top composer then sends each component to its appropriate NodeComposer, based on its node name. This either happens on start-up (if the appropriate node composer is already up), or whenever such a composer is available.
Which isolate takes which component is decided by an IsolateDistributor component, that goes through a voting process.
For isolate that already exist, node composer sends a list of components to be instantiated to an IsolateComposer component.
