v1.0.1

Patch Updates

• Fix collection population on write by adding a check in mapper's add_item_to_target method to omit adding new item to collection if item is already there. This is required in cases when item is built via ActiveRecord's build_association method (which is happening when using :active_record extension), which immediately places new item to the collection, thus leading to erroneous results if item is re-added by flatter's code.
