Extensions to Espruino for WS2812 modules

Yes, and at least first one is a very good reason ;-)

• loved to do it and learned a lot
  
• it's much faster than java script, try to rotate in java script and you will see
  
• doesn't take away as many variables compared to java script
  
  

There are already a lot of special functions inside Espruino, that could be a module. May be on a long term we will have a couple of Espruino extensions which can be used to create customized firmware by sticking together firmware modules.
