You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: Walker.m
    path of file: ./repos/BPL/bottomup/initialize
    
    the code of the file until where you have to start completion: classdef Walker < BetterHandle
    % Walker: Class that controls a walk on the directed graph
    %   that is defined by the skeleton. The walk is complete
    
    
function select_moves(this,sel)
           this.list_WS{end}.select_move(sel);
        end
        
        % Get local moves we can make that cover a new edge
        %
        % Input
        %  pt: [1x2] optional, compute moves from this point
        function [cell_traj,vei] = get_new_moves(this)
            [cell_traj,vei] = this.list_WS{end
