ConflictsFromManagers creates a list of conflicts given Managers sets.

Conflict is a conflict on a specific field with the current manager of that field.

Updater is the object used to compute updated FieldSets and also merge the object on Apply.

UpdateBuilder allows you to create a new Updater by exposing all of the options and setting them once.

Converter is an interface to the conversion logic.

Conflicts accumulates multiple conflicts and aggregates them by managers.
