A simple dependency graph resolver.
Deppy will walk the graph and build an array of nodes. The first element in the array has no dependencies while subsequent elements depend on zero or more previous elements. Here is an example of using deppy to build and resolve a graph:
var d = require('deppy').create(); d('a'); d('c', ['b']); d('b', ['a']); console.log(d.resolve('c')); // [ 'a', 'b', 'c' ]
