Title: OpenSwing Framework

Description: Generic aggregator for row/column fields of a pivot table: it decodes a String value to a String value, by grouping input values based on their prefix. Example: "Alan" -> "A", "Bob" -> "B", "Craig" -> "C". Example: if LetterAggregator is initialized as follows: addGroup('a','g',"A-G"); addGroup('h','l',"H-L"); addGroup('m','q',"M-Q"); addGroup('r','z',"R-Z"); then returned values are: "Alan" -> "A-G", "Bob" -> "A-G", "Hillary" -> "H-L", "Sam" -> "R-Z"
