Title: Displayed the node ids of the input nodes in the mapindex

I changed the display of mapindex in the node:label().
1) The display will not fail if node.data has no module or input.
2) If a node has more than one input,
the ids of the input nodes will be displayed:
E.g., `mapindex = {Node6,Node11}`.

Tell me if you prefer something else.
