Functions/Subroutines
subroutine	tree_amg::tamg_init (this, ax, xh, coef, msh, gs_h, nlvls, blst)
	Initialization of TreeAMG hierarchy.
subroutine	tree_amg::tamg_free (this)
	deallocate tamg hierarchy
subroutine, public	tree_amg::tamg_lvl_init (tamg_lvl, lvl, nnodes, ndofs)
	Initialization of a TreeAMG level.
subroutine	tree_amg::lvl_free (this)
	deallocate tamg level
subroutine, public	tree_amg::tamg_node_init (node, gid, ndofs)
	Initialization of a TreeAMG tree node.
subroutine	tree_amg::node_free (this)
	deallocate tamg tree node
recursive subroutine	tree_amg::tamg_matvec (this, vec_out, vec_in, lvl_out)
	Wrapper for matrix vector product using the TreeAMG hierarchy structure b=Ax done as vec_out = A * vec_in.
recursive subroutine	tree_amg::tamg_matvec_impl (this, vec_out, vec_in, lvl, lvl_out)
	Matrix vector product using the TreeAMG hierarchy structure b=Ax done as vec_out = A * vec_in This is done on a level by level basis.
recursive subroutine	tree_amg::tamg_matvec_flat_impl (this, vec_out, vec_in, lvl_blah, lvl_out)
	Ignore this. For piecewise constant, can create index map directly to finest level.
subroutine	tree_amg::tamg_restriction_operator (this, vec_out, vec_in, lvl)
	Restriction operator for TreeAMG. vec_out = R * vec_in.
subroutine	tree_amg::tamg_prolongation_operator (this, vec_out, vec_in, lvl)
	Prolongation operator for TreeAMG. vec_out = P * vec_in.
subroutine	tree_amg::tamg_device_matvec_flat_impl (this, vec_out, vec_in, vec_out_d, vec_in_d, lvl_out)
subroutine	tree_amg::tamg_device_restriction_operator (this, vec_out_d, vec_in_d, lvl)
subroutine	tree_amg::tamg_device_prolongation_operator (this, vec_out_d, vec_in_d, lvl, vec_out)
