Init commit with many years of arduino sketches and projects. I dont know if the esp8266 includes much, but there are also libraries. I hope they dont have crazy automatic versioning through the Arduino IDE.

+// This file implements a basic liquid crystal library that comes as standard
+// in the Arduino SDK but using the extension board BV4218/BV4208 from ByVac.
+// 
+// @brief 
+// This is a basic implementation of the LiquidCrystal library of the
+// Arduino SDK. The original library has been reworked in such a way that 
+// this class implements the all methods to command an LCD based
+// on the Hitachi HD44780 and compatible chipsets using I2C extension
+// backpack BV4218 from ByVac.
+//
+// The functionality provided by this class and its base class is identical
+// to the original functionality of the Arduino LiquidCrystal library.
