* Define session data structure and some operations * Make code evaluation request async, so that we don't need an intermediary process * Simplify id typespecs * Make operation application composable * Keep a separate evaluation queue per section and actually support concurrent evaluation * Small fixes * Validate queued cell type and set evaluation timestamp * Apply review suggestions * Add tests * Store evaluating_cell_id instead of section status * Add dynamic supervisor for managing evaluator processes * Some fixes * Refactor operation application * Upon cell deletion mark dependent cells as stale
