/**
    Temperature Sensor for hw6
    SegDisplay.cpp

    Purpose: Convert an integer value to a hex
             Hex output represents binary required to make a 7-seg led show the integer value
             Pin configuration for 7-Seg
             ones: 12 13 14 15 16 17 18 19
                    A  B  C  D  E  F  G  P 
             tens: 21 22 23 24 25 26 27 28
