Manager is used to manage a specified resource, like AggregatorManager and CommunicationManager. A manager is created and initialized by init(Config)} before all supersteps start, and destroyed by close(org.apache.hugegraph.computer.core.config.Config) after all supersteps ended.

    The unique identify name.
  - init
```
default void init(org.apache.hugegraph.computer.core.config.Config config)
```
    Used to add the resources needed by the computation. Be called only one time before all supersteps start.
  - inited
```
default void inited(org.apache.hugegraph.computer.core.config.Config config)
```
    Used to notify all managers that master or worker is inited. Be called only one time before all supersteps start.
  - close
```
default void close(org.apache.hugegraph.computer.core.config.Config config)
```
    Close the resources used in the computation. Be called only one time after all supersteps ended.
  - beforeSuperstep
```
default void beforeSuperstep(org.apache.hugegraph.computer.core.config.Config config,
                             int superstep)
```
    Do some initialization for a superstep. Be called before a superstep. Subclass should override this method if wants to do something before a superstep.
  - afterSuperstep
```
default void afterSuperstep(org.apache.hugegraph.computer.core.config.Config config,
                            int superstep)
```
    Do some clean up for a superstep. Be called after a superstep. Subclass should override this method if wants to do something after a superstep.
