Amethyst

Amethyst is a framework intended to help in creation of applications with the MVC or a similar pattern. The project consists of low- and high-level API.
Low-level API is responsible for exchanging properties (as Map) between various components. A component can be for example model, view or controller as in the MVC pattern. The main class is a class named Communicator. Communicator class defines the structure of components' system, provides communication channel between them and life-cycle management for each one. It also provides ability to run components in different threads (multitasking).
