Refactor Hash.from_xml.
Three basic refactors in this PR:
* We extracted the logic into a method object. We now don't define a tone of extraneous methods on Hash, even if they were private.
* Extracted blocks of the case statement into methods that do the work. This makes the logic more clear.
* Extracted complicated if clauses into their own query methods. They often have two or three terms, this makes it much easier to see what they _do_.
We took care not to refactor too much as to not break anything, and put comments where we suspect tests are missing.
We think ActiveSupport::XMLMini might be a good candidate to move to a plugin in the future.
