Add a message at the beginning of spin the wheel about the configuration

[bknueven]

Examples:
Using cylinders PHHub, FrankWolfeOuterBound, LagrangianOuterBound, LagrangerOuterBound, and XhatShuffleInnerBound with 5 MPI ranks

Using cylinders PHHub, LagrangianOuterBound, and XhatShuffleInnerBound with 3 MPI ranks

Using cylinders LShapedHub and XhatLShapedInnerBound with 2 MPI ranks

Using cylinder LShapedHub with 2 MPI ranks

Also changes the use of global_toc to only pick up the communicator specified by the user.

This is a good idea and I appreciate the extra coding required for proper use of the Oxford comma!
