Localized Fields

[Bruno Azisaka Maciel]

Hi,

I had to localize an array and the solution was to create an custom field. But I think that would be ok to keep the field's type instead of converting it to String. 

I would like to understand the reasons behind the converting the objects into Strings. https://github.com/mongoid/mongoid/blob/master/lib/mongoid/fields/internal/localized.rb

Thanks!
