Next generation game UI middleware

Coherent UI is a graphical user interface system specially designed for
games. Game developers and UI artists can use standard modern HTML, CSS,
and JavaScript to design and implement game UI and interaction.
Coherent UI makes easy exposing gameplay, game objects, and systems to
the UI. Game developers can focus on implementing core gameplay while
quickly facilitating existing skills to implement the UI, as there is no
special knowledge needed to use the system.
