## Namespaces

When using imports and groups to model large hierarchical systems, it is a common pattern to have groups around the entire specification:

    group factory:
      group machine1:
        group part1:
          automaton sensor1:
            ...
          end

          automaton actuator1:
            ...
          end
        end
      end
    end

The groups around the entire specification lead to additional indentation. As this is a common pattern, the CIF language provides namespaces to reduce the impact of large numbers of top level groups:

    namespace factory.machine1.part1;

    automaton sensor1:
      ...
    end

    automaton actuator1:
      ...
    end

The `factory.machine1.part1` namespace has exactly the same effect as the original three groups. Both specifications can thus be considered identical.
