Cara 1.8.4.2

One of the major advantages of the new architecture is the possibility to decentralize responsibilities. CARA will be an open platform. New scopes can be developed and maintained by different people according to their focus of interest. Even though there will always be a stable kernel (i.e. CARA itself cannot be undermined by custom code as it is the case with some Python based implementations). I will continue to maintain and extend the kernel according to the feedback of the scope providers.
