Rule names conflict with schema-attribute names

[willrstern]

A schema-attribute named email will error if there is a rule named email

schemator.defineRule('email', function (x) {
  return null;
});

var schema = schemator.defineSchema('mySchema', {
  //this schema errors because field "email" matches a rule name
  email: {
    email: true
  }
});

This prevents from using on data structures with attributes such as "type", "max", or any custom rule.

It's happening here...

Yeah, I had been thinking about simply deleting that line of code. And the tests pass without it, so I'll do it shortly.

Oh nice. I was gonna submit a pr with it out (I noticed the passing tests as well), but wasn't sure why it was in place.

Thanks again!
