Calling an embedded trait twice will fail.

[blakewest]

Given the following factory...

Replicator.define('membership', {
  meta: Replicator.embed('membershipMeta', {coveredMembership: true})
}
and
Replicator.define('membershipMeta', {
  reg_fee: {editable: true}
 }
  .trait('coveredMembership', {
  reg_fee: {editable: false}
}

If you do something like...

  var membershipFactory = Replicator.makeFactory('membership');
  membershipFactory({coveredMembership: true}); // membership.meta.reg_fee.editable === false;
  membershipFactory({coveredMembership: true}); // membership.meta.reg_fee.edtiable === true;

I would expect them both to return the same thing when run twice.
