I've re-written the code to optimise how it works and for how long you can be pressing the button.

The old flow limits you to 6 seconds. Granted that is a long time, but it is limited.

I re-wrote how it works which allows _unlimited_ pressing of the button.

Also with the old way you had to wait 6 seconds between sequences, which is also a bit long.

The new one takes that down to 1 second.

This new way the `reset` signal is kept from being sent because the button has been pressed again with an interval of less than `1 second`.

This is 4 examples.  
I pressed the `inject` node 1, 2,3 and 4 times, and got those 4 messages.  
Sorry too: I haven't updated an of the `comment` nodes.

I was a bit over come with excitement that I got the re-write done and wanted to share.  
(Yeah, I know. Not really professional.)
