BNFNode :: toSymbol - Convert BNF tree node
When a BNF tree node is identical with a BNF tree node for a lower level symbol ( isSymbol() ) , the tree node may be "converted" to the lower level node passed in sSymbol . When the BNF tree nodes are not the same, an invalid BNF tree node will be returned.
Return value: BNF tree node ( odaba::BNFNode & )
