The new Component API code was really similar to the existing ViewAdapter code. Both of them were running the view loop to calculate diff and apply the differences to the UI. The main difference is that ViewAdapter was only supporting the root control (eg. IFabApplication) where Component supports any control and any state management system.

    A[State]--changes-->B[view function]
    B--applies diff-->C[UI]
    C--triggers a change-->A

I consolidated the code by removing ViewAdapter and using Component everytime.
To support non-component codebase, UseFabulousApp will now create an implicit Component using the Program passed to it.
