The BaMaWa Young tableaux Maple package

In link with our work Periodic Pólya Urns, the Density Method, and Asymptotics of Young Tableaux,
we (Cyril Banderier, Philippe Marchal, Michael Wallner) developped the following small Maple package for basic manipulation on Young tableaux, and for their uniform generation, allowing some fancy 3D plots.
