var obj = { foo: 1, bar: { baz: 2}, qux: [3, 4, 5]};

jsonpointer.get(obj, '/foo');     // returns 1
jsonpointer.get(obj, '/bar/baz'); // returns 2
jsonpointer.get(obj, '/qux/0');   // returns 3
jsonpointer.get(obj, '/qux/1');   // returns 4
jsonpointer.get(obj, '/qux/2');   // returns 5
jsonpointer.get(obj, '/quo');     // returns undefined

jsonpointer.set(obj, '/foo', 6);  // sets obj.foo = 6;
jsonpointer.set(obj, '/qux/-', 6) // sets obj.qux = [3, 4, 5, 6]

var pointer = jsonpointer.compile('/foo')
