Description: Facilitates creation and manipulation of metric graphs,
        such as street or river networks. Further facilitates
        operations and visualizations of data on metric graphs, and the
        creation of a large class of random fields and stochastic
        partial differential equations on such spaces. These random
        fields can be used for simulation, prediction and inference. In
        particular, linear mixed effects models including random field
        components can be fitted to data based on computationally
        efficient sparse matrix representations. Interfaces to the R
        packages 'INLA' and 'inlabru' are also provided, which
        facilitate working with Bayesian statistical models on metric
        graphs. The main references for the methods are Bolin, Simas
        and Wallin (2024) <doi:10.3150/23-BEJ1647>, Bolin, Kovacs,
        Kumar and Simas (2023) <doi:10.1090/mcom/3929> and Bolin, Simas
