# #####################################################
# Python Library for 3x4 matrix keypad using
# 7 of the avialable GPIO pins on the Raspberry Pi.
#
# This could easily be expanded to handle a 4x4 but I
# don't have one for testing. The KEYPAD constant
# would need to be updated. Also the setting/checking
# of the colVal part would need to be expanded to
# handle the extra column.
