Missing equipment creation method into VoltageLevelRawBuilder

[tadam50]

Describe the current behavior

As the NetworkGraphBuilder the VoltageLevelRawBuilder does not have following methods:

• createInductor
• createCapacitor
• createDanglingLine
  The creation equipment method is not exhaustive.

Describe the expected behavior

The creation equipment method must be exhaustive.

Describe the motivation

Make VoltageLevelRawBuilder usage more simple.

Extra Information

Example of changes in VoltageLevelRawBuilder class:

public FeederNode createInductor(String id) {
        return createInductor(id, 0, null);
}

 public FeederNode createInductor(String id, int order, Direction direction) {
        FeederNode fn = NodeFactory.createInductor(voltageLevelGraph, id, id);
        commonFeederSetting(fn, id, order, direction);
        return fn;
 }

public FeederNode createCapacitor(String id) {
        return createCapacitor(id, 0, null);
}

public FeederNode createCapacitor(String id, int order, Direction direction) {
        FeederNode fn = NodeFactory.createCapacitor(voltageLevelGraph, id, id);
        commonFeederSetting(fn, id, order, direction);
        return fn;
}

public FeederNode createDanglingLine(String id) {
        return createCapacitor(id, 0, null);
}

public FeederNode createDanglingLine(String id, int order, Direction direction) {
        FeederNode fn = NodeFactory.createDanglingLine(voltageLevelGraph, id, id);
        commonFeederSetting(fn, id, order, direction);
        return fn;
}
