/**
 * This interface works in conjuction with the GridSerializer. When serializing a grid, an instance that implements this interface
 * must be passed in, the serializer will call back to the provided methods and finally call to parse to obtain the final result
 * of the serialization.
 *
 * The lifecycle of a serializer with a GridSerializingSession is as follows.
 *
 * --1 Call to prepare method. An opportunity to do any required work before the call to accumulate data for the rows are about to happen.
 * --2 Call to the row methods as the serializer loops through the different rows of the grid will call these methods so that the data
 * can be accumulated. The methods. if there is relevant data will be called in the following order:
 *      a) addCustomHeader
 *      b) onNewHeaderGroupingRow
 *      c) onNewHeader
 *      d) onNewBodyRow
 *      e) addCustomFooter
 *      IF ANY OF THIS METHODS RETURN A ROW ACCUMULATOR, YOU CAN EXPECT THE SERIALIZER TO CALL ON THAT ACCUMULATOR WITH THE DATA FOR THAT ROW
 *      IMMEDIATELY AFTER IT HAS RECEIVED THE OBJECT AND BEFORE IT CALLS YOU TO OBTAIN A NEW ROW ACCUMULATOR
 * --3 Call to parse method. This method is the last one to be called and is expected to return whatever accumulated
 * parsed string is to be returned as a result of the serialization
 *
 * This interface is closely related to the RowAccumulator and RowSpanningAccumulator interfaces as every time a new row is about
 * to be created a new instances of RowAccumulator or RowSpanningAccumulator need to be provided.
