* RefEval is the super interface for Ref2D and Ref3DEval. Basically a RefEval
* impl should contain reference to the original ReferencePtg or Ref3DPtg as
* well as the final "value" resulting from the evaluation of the cell
* reference. Thus if the HSSFCell has type CELL_TYPE_NUMERIC, the contained
* value object should be of type NumberEval; if cell type is CELL_TYPE_STRING,
* contained value object should be of type StringEval
