Hi guys, there are some doubts in actionlib tutorial:

1.The difference between FibonacciActionGoal.msg and FibonacciGoal.msg?

2.It seems that in main function there is not always to define a server(explained in ""), which is connected to client? In , FibonacciAction fibonacci(ros::this_node::getName()) might play the similar role(but I actually don't know how).

3.In , it set no registerGoalCallback() function, which used in "", but where is the difference of the two method? And I found no acceptNewGoal function, so how the server accept the first goal sent by client?(the client side has a function sendGoal() as a match to it).

Thanks so much!
