nodes : [
{
label : 'oh',
nodes : [ 'hello', 'puny' ]
},
'human'

# methods
var archy = require('archy')
## archy(obj, prefix='', opts={})
Return a string representation of `obj` with unicode pipe characters like how
`npm ls` looks.
`obj` should be a tree of nested objects with `'label'` and `'nodes'` fields.
`'label'` is a string of text to display at a node level and `'nodes'` is an
array of the descendents of the current node.
If a node is a string, that string will be used as the `'label'` and an empty
array of `'nodes'` will be used.
`prefix` gets prepended to all the lines and is used by the algorithm to
recursively update.
If `'label'` has newlines they will be indented at the present indentation level
with the current prefix.
To disable unicode results in favor of all-ansi output set `opts.unicode` to
`false`.
