It creates an object with two slots: <code>$graph</code> which contains the graph and <code>$depParams</code>
which contains the edge weights, initialized with zero values. It is a subclass of <code>HRMtree</code>.
It is intended to be used for models on trees to estimate edge weights using method of moment estimator.
Please consult Vignettes "Code - Note 1" and "Estimation - Note 1".

Provides tools for estimation of edge weights on graphical models with respect to trees and block graphs and parameterized by a particular family of max-stable copulas. The edge weights are parameters of tail dependence between adjacent variables and these edge weights determine the joint tail dependence between all variables in the context of a particular parametric model. For methods of moment estimator, composite likelihood estimator please see Asenova et al. (2021) <doi:10.1007/s10687-021-00407-5>. For estimation based on extremal coefficients see Asenova et al. (2021) as well as Einmahl et al. (2016) <doi:10.2139/ssrn.2717531>. For cliquewise estimation please see Engelke and Hitz (2020) <doi:10.1111/rssb.12355>.
