-* The EdgeBreaker connectivity section is composed of five sections. The first section is the connectivity header. The second section is the encoded EdgeBreaker symbol data. The third section is the encoded start face configuration data. The fourth section is the attribute connectivity data. The fifth section is the encoded split data.
