Objects are called with `ImportableUniqueObject` methods in the same order as in import sources array. - Warning: While the array returned from `importUniqueObjects(...)` correctly maps to the order of `sourceArray`, the order of objects called with `ImportableUniqueObject` methods is arbitrary. Do not make assumptions that any particular object will be imported ahead or after another object.
The array returned from `importUniqueObjects(...)` correctly maps to the order of `sourceArray`.
