`node`	a node object
`refnode`	name of the reference node
`node_names`	new node names
`colors`	optionally a vector of colors matching the length of `node_names`
`weights`	optionally a vector of weights matching the length of `node_names`
`codes`	optionally a vector of short labels matching the length of `node_names`

a Node object

n <- vt_add_nodes(n, refnode="Asia",node_names=c("China","Thailand"),
  weights=c(0.5, 0.8), codes=c("CN","TH"))
n <- vt_add_nodes(n, refnode="Europe",node_names=c("Netherlands","Austria"),
  weights=c(0.9, 1.1), codes=c("NL","AT"))
print(n, "weight", "code", "color")
