CVRPLIB problem instance downloader

CVRLIB offers a selection of CVRP problem instances. This function downloads the instance data and conveniently makes it available to be fed into solver functions, e.g. with clarke_wright_cvrplib(). The primary purpose for those instances is benchmarking / comparing speed as well as performance of solvers.

Usage

cvrplib_download(qualifier, cvrplib_url = "https://galgos.inf.puc-rio.br")
