Can't instantiate mongo EmbeddedDocumentField with a string argument, only works with object.

[rochacbruno]

If I do:

comments = db.ListField(db.EmbeddedDocumentField(Comment))

everything works ok.

But it does not works if I do;

comments = db.ListField(db.EmbeddedDocumentField("Comment"))

It says:

str object does not have attribute __base__  cls.__base__

I guess it needs to be imported dinamically by the string name of the model.
