Hi~ Thanks for this useful module. I can run the read.py file successfully

pi@raspberrypi ~/Documents/rfid_demo $ sudo python read.py 
Welcome to the MFRC522 data read example
Press Ctrl-C to stop.

but when I move the file to another directory error occured the command line output is:

pi@raspberrypi  ~/Document/mahjong/test_code $ sudo python read.py 
Traceback (most recent call last):
  File "read.py", line 21, in <module>
    MIFAREReader = MFRC522.MFRC522()
  File "/home/pi/Documents/mahjong/test_code/MFRC522.py", line 111, in __init__
    nSPI(device=dev,speed=spd)
NameError: global name 'nSPI' is not defined

so I wonder what is the function nSPI()？ the code is absolutely the same. I am new to python. Thank you for your help!
