Extract change point information
gt allows inferring change points in layered graphs when time is passed as an edge property (Peixoto (2015). Inferring the mesoscale structure of layered, edge-valued, and time-varying networks. https://doi.org/10.1103/PhysRevE.92.042807). But extracting the bin / change point information from the SBM is not automatized in gt. The goal is to produce a figures as in figure 8 of the referenced paper. Help is truly appreciated...
