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 & )
