serflag variables, start with 1

	// FlagAssist represent assist node
	FlagAssist = iota
	// FlagTxParent represent the parent of transaction of node
	FlagTxParent
	// FlagTxLeaf represent transaction of node
	FlagTxLeaf
)

merkleFlag represent the type of merkle tree node, it's used to generate the structure of merkle tree Bitcoin has only two flags, which zero means the hash of assist node. And one means the hash of the related transaction node or it's parents, which distinguish them according to the height of the tree. But in the bytom, the height of transaction node is not fixed, so we need three flags to distinguish these nodes.
