Create array from a range of cells.

@param string $pNamedRange Name of the Named Range
@param mixed $nullValue Value returned in the array entry if a cell doesn't exist
@param bool $calculateFormulas Should formulas be calculated?
@param bool $formatData Should formatting be applied to cell values?
@param bool $returnCellRef False - Return a simple array of rows and columns indexed by number counting from zero
True - Return rows and columns indexed by their actual row and column IDs

@throws Exception
