Stable soap bubble clusters with multiple torus bubbles: getting a bit more exotic

The clusters geometries are based on prisms and Archimedean solids. Surface Evolver configuration files allowing to get stable soap bubble clusters with multiple torus bubbles. Stable soap bubble clusters from the simulations using the previous configuration files (coarse and fine discretizations). Multimaterial mesh versions of Surface Evolver dump files: MultiTracker format. Python script to generate Surface Evolver configuration files. Python script to view the clusters independently of Surface Evolver. Use of Polyscope. The compressed tarball README.txz only contains the tex/bib files and figures to generate README.pdf For geometries based on Platonic solids, see the previous repository Stable soap bubble clusters with multiple torus bubbles.
