Feature Information

Our current implementation of ViewModel and ViewModelState has a lot of duplication which can be better abstract away behind the existing abstractions.

Solution Information

• Move the all the implementations of ISupportViewModelState and the useCaseResult mutable live data objects and abstract them away into AniTrendViewModelState
• Remove hooks and onClear events for AniTrendViewModelState into a new abstraction that will be called AniTrendViewModel that replaces all qualified references of ViewModel, this will have one argument constructor argument called state of the abstract type of AniTrendViewModelState<*>.
• Refactor [app-core] view model extensions for hook to only expect one argument as part of a Single responsibility revamp to enforce one state per view model
