   This package provides object-oriented implementation of visualization and query tasks of commits data from GiHub.
-  The implementation uses the design patterns (Template Method, Strategy, Decorator, and Composite).

   The implementation is a modified and extended version of the functions in the package "GitHubPlots.m".
