Please can we change the clone-node.js script to work:
a) clone-node.js accepts a number of nodes to clone (e.g. node clone-node.js 2 - create 2 more nodes)
b) Nodes should be startable from the root (e.g. node node-1/index.js)
c) Maybe even a node start-all-nodes.js script?
d) The clone-node.js script should delete all nodes and reclone

After playing a bit, I made some of these changes myself, because I got so sick and tired of cloning, deleting, cding, starting...
