easyMesh: error compiling; issue with SimpleList

amazing work you’ve done here, thank you. but I keep getting errors compiling you’re startHere. trying to read your source codes and can’t solve the problem. any help and insight will appreciated.

Arduino: 1.6.9 (Windows 10), Board: "Generic ESP8266 Module, 80 MHz, 40MHz, DIO, 115200, 512K (64K SPIFFS), ck, Disabled, None"
