Arguments

leaf_ids_units, leaf_ids_nodes, ancestors, h_pau, levels, v_units, subject_id_list, ind_obs_i, ind_obs_j, scenario	outputs from design_doubletree(). Among them, subject_id_list is currently not used in the initialization function initialize_nlcm_doubletree(), but are useful for updating functions here.
X, n, J, p1, p2, pL1, pL2, Fg1, Fg2, cardanc1, cardanc2	data and design information computed from the outputs of initialize_nlcm_doubletree(); we use R.utils::do.Call to get their values from dsgn.
prob1, prob2, mu_gamma, mu_alpha, rmat, emat, dirich_mat, sigma_gamma, sigma_alpha, tau_1_t, tau_2_t, a1_t, b1_t, a2_t, b2_t	variational parameters
psi, g_psi, phi, g_phi, tau_1, tau_2	parameters updated by update_hyperparams_doubletree()
do_tree1_update	TRUE to update mu_gamma,sigma_gamma, prob1,tau_1 fixed hyperparameters
