/**
  * This class defines a report within the MyMoneyEngine.  The report class
  * contains all the configuration parameters needed to run a report, plus
  * XML serialization.
  *
  * A report is a transactionfilter, so any report can specify which
  * transactions it's interested down to the most minute level of detail.
  * It extends the transactionfilter by providing identification (name,
  * comments, group type, etc) as well as layout information (what kind
  * of layout should be used, how the rows & columns should be presented,
  * currency converted, etc.)
  *
  * As noted above, this class only provides a report DEFINITION.  The
  * generation and presentation of the report itself are left to higher
  * level classes.
