Added support for dynamic URLs

    // #/users
    API.addChapter({
        name: 'users',
        url: '/users'
    });
    
    // #/users/:id/info
    API.users.define({
    	name : 'info',
    	url : function (id) {
    		return '/' + id + '/info';
    	}
    });
    
    // Get user information
    API.users.info(id).done(function (data) {
    	console.log(data);
    });
