//**********************************************************
// DS18S20 example, reading
// You can connect multiple sensors to a single port
// (At the moment 4 pcs - it depends on the definition in the library)
// Measuring time: 1.2 seconds * number of sensors
// The main difference with the previous version of the demo:
//  - Do not use the Delay function () which discourages by manufacturer of ESP8266
//  - We can read several sensors
// Usage:
//  Call Init to setup pin eg. ReadTemp.Init(2);   //pin 2 selected
//  Call ReadTemp.StartMeasure();
//   if ReadTemp.MeasureStatus() false read sensors
//   You can recognize sensors by the ID or index.
