v3, minor suggestion: collision between Unity.Yarn and OdinInspector attributes

[dario-zubovic]

What is the current behavior? Both Yarn.Unity and Sirenix.OdinInspector namespaces define attributes named ShowIf and HideIf, causing annoying conflicts in scripts that are using both. Odin Inspector is a hugely popular Unity plugin that's used in a lot of projects, so it might make sense to avoid this collision.

Suggestion Move classes in Attributes.cs to Yarn.Unity.Attributes or Yarn.UnityYarn.Utils namespace.

Environment:

• Yarn Spinner Version: development/v3 (4656e248dd76d0025005c167a1904e6ce028221a)
• Unity Version: 2022.3.22f1
