Contributions summary:Kalen focused on modifying the Kotlin SDK code generation for the Looker API. Their work primarily involved refactoring and enhancing the `ApiSettings` class to accept a `Map` instead of `Ini` text, enabling simpler behavior overrides for clients. Additionally, they enabled ktlint formatting and moved comments into the header for method parameters, contributing to code quality and maintainability. These changes demonstrate a focus on improving the SDK's flexibility and adherence to coding standards.
