String doBuild(PipelineData pipelineData)
        throws Exception
```
    A subclass must implement this method to build itself. Subclasses override this method to store the navigation in RunData or to write the navigation to the output stream referenced in RunData.
    
    Parameters:
    
    pipelineData - Turbine information.
    
    Returns:
    
    the content of the navigation module
    
    Throws:
    
    Exception - a generic exception.
  - build
```
default String build(PipelineData pipelineData)
              throws Exception
```
    Subclasses can override this method to add additional functionality.
    
    Parameters:
    
    pipelineData - Turbine information.
    
    Returns:
    
    the content of the navigation module
    
    Throws:
    
    Exception - a generic exception.
