//
// C++ Interface: FillerBase
//
// Description:
//
// This class is the Base class for all data fillers.
// The derived filler needs to implement
// open()
// close()
// fill()
//
// The fill() method usually iterates over the source data and calls
// the setXYZ() methods for. After all the data for a row has been set via
// these methods, the fill() method needs to call commitRow() to write the
// data to the scantable.
// All arguments which are defaulted in the setXYZ() methods are optional. All
// others should be set explicitly.
