Enhanced boolean logic with persistent values after reboot and more.  
Now with Interrupt flow node.

@Supergiovane we have a ongoing thread about node's saving their own data to persist reboots etc - [❓ DISCUSSION: Should nodes save/restore their own context?](https://discourse.nodered.org/t/discussion-should-nodes-save-restore-their-own-context/20590/) where we've been discussing saving the data using node-RED's `contextStorage`, and we now have two working examples of how that can be achieved - [node-red-contrib-state-trail](https://flows.nodered.org/node/node-red-contrib-ui-state-trail) and [node-red-contrib-simple-gate](https://flows.nodered.org/node/node-red-contrib-simple-gate) which are working well, and hold promise for further development options.

I see that your node does not use `contextStorage`, but instead saves it as a json file synchronously to a folder - `~/states`.  
Although it functions fine, I just worry that if other nodes followed this model instead of using `contextStorage`, we could potentially end up with node data being scattered around the filesystem, which would not be good.

Thank you Paul to point me out this.  
I’ll check it. 😉
