TDataFrame: functional chains for ROOT data analyses

TDataFrame is a simple and yet powerful way to perform ROOT data analyses.\nIt provides great flexibility in the actions that can be performed inside the event-loop, while letting users express them in a concise declarative syntax that fully encourages usage of modern C++. Transparent access to multi-thread parallelism makes TDataFrame a viable option for quick data explorations, as well as an expressive and high-level tool for more complex analyses.

v1.0 comes with a satisfying first set of features, a user guide, Doxygen docs for the user interface and many ideas for future enhancements. A comprehensive suite of tests augmented by static analysis scans guarantees the robustness and stability of the software.
