"Add an operator to an existing Extension"
Hi everyone ! 
I really need your help... I'm french, so i'm sorry for my bad english.
I'm new in RapidMiner and I must create an empty operator (just for try, after that i will do something harder) in the extension Series. When I open RapidMiner, i can see the extension, but i can't find the code of the extension in the source code of RapidMiner. Is it normal ?
I put the extension .jar in a hidden file .config/RapidMiner/.
Moreover, I have no idea how we can create an operator. I'm new in java too. I read the documentation "How extend RapidMiner 5" and... Well... I read it, but I am not sure I understood it (not just because it is written in english).
I am really lost. And a little desperate... I have no idea what I am doing.
I hope you will understand what i am asking.
Once again, i am sorry for my english.
Regards,
Leeloo
