let me rephrase that ,the two downloaded files from github are unzipped into the libraries file and are one above each other in the arduino libraries folder ,with all the other libraries such as
here
Adafruit_GFX (new addition)
Adafruit_ST7735 (new addition)
EEPROM
ETHERNET
Firmata
LiquidCrystal
SD
Servo
SoftwareSerial
SPI
Stepper
Wire
but when start up the IDE the Adafruit_GFX file is not seen in the IDE
so the examples wont run
