lseman/baldes ? reverse-engineered prompt

Build me a fast C++ solver for vehicle routing that can handle CVRP and VRPTW instances from the command line.

I want it to read an instance file, run a bucket graph labeling based pricing routine, and solve the problem with a branch and price style workflow. It should support a simple command like baldes vrptw path/to/instance and baldes cvrp path/to/instance, and it would be great if it also included a few sample instances and example runs so I can try it right away.

Please make it build cleanly with CMake, include a release build option, and keep the code organized enough that optional extras like cuts, warm starts, and Python bindings can be turned on later. If you need to look up current docs for any solver libraries or build setup, go ahead and do that. I mainly want a working research style solver that is fast, practical, and easy to experiment with.
