Spine has Unity Attributes like SpineAnimation, but it has some limit, e.g. it can not be used on string, it can not report an error if the target is changed, mismatch with skeleton or missing etc.

SainsField's spine attributes allow more robust references:

1. Check reference when possible
2. Supported by Auto Validator tool, with searching supported
3. Unity's default right click context menu works as expected

These tools are there only if you have Spine installed.
