 * This method is called to determine the changes the step is making to the row-stream.
 * To that end a RowMetaInterface object is passed in, containing the row-stream structure as it is when entering
 * the step. This method must apply any changes the step makes to the row stream. Usually a step adds fields to the
 * row-stream.
 * 
 * @param inputRowMeta		the row structure coming in to the step
 * @param name 				the name of the step making the changes
 * @param info				row structures of any info steps coming in
 * @param nextStep			the description of a step this step is passing rows to
 * @param space				the variable space for resolving variables
 * @param repository		the repository instance optionally read from
 * @param metaStore			the metaStore to optionally read from
