Release v2.0.0 (Dataflow v2)

This release marks a redesign of the dataflow algorithm.
From now on, we handle built-ins and operators as function calls (as it is done by R) and provider default definitions for R's primitives (see #569). Besides, this major release contains a lot of improvements and bugfixes as outlined below. We note performance improvements!
