* Fix some compile errors with the pet store sample

* Fix duplicate auth companion object and import generation

* Reinstate query and form parameter code generation

* Add check for unsupported serialization libraries

* Fix broken unit tests

* Regenerate samples

* AN-233 Update request factory to allow custom gsonadapters

* update `GsonRequest.mustache` and `RequestFactoy.mustache` to use `Map<Type, Any>` instead of `Map<Type, Object>` to better fit kotlin conventions

* Update readme with better examples and design notes

* Update readme with info about gson serializers and adapters for polymorphic types

* Updated samples

* Merge from upstream

* Address review comments

* Update samples

* Samples

* Update docs

* Remove DateAdapter generated file, template and it's inclusion as a supporting file in favour of localDateTime

* Review comment - add a kotlin version parameter to the build scripts

* Updated samples

* Missing changes from build.mustache

* Regenerate samples for build.gradle changes
