.flatten doesn't preserve empty objects.

[lxe]

console.log(flat.flatten({
  has: {
    value : 'someValue'
  },
  empty : {
    value : {
      nested: { }
    }
  }
}));

will return

{ 'has.value': 'someValue' }

instead the expected:

{ 'has.value': 'someValue', 'empty.value.nested': { } }

Edit:

To elaborate. It might seem as objects imply nesting, but if we don't account for empty objects, flatteining then deflattening an object will not preserve the original object structure.

In this example, doing flat.unflatten(flat.flatten(o)) will not retain the 'empty.value.nested' tree.

You should submit a PR, or at least a failing test and I'll look at it.

Oh you have.
