    1.Remove smoe function that useless for user.
      Such as:  
                void write_93c46(int slot,int addr,int data);
                int read_93c46(int slot,int addr);           
                void erase_93c46(int slot,int addr);         
      
              
    2.Change functions name:                               
          pac_i8024_VoltageHexOut ==> pac_i8024_VoltageOut_Hex
          pac_i8024_CurrentHexOut ==> pac_i8024_CurrentOut_Hex

/*
For I-8024 use 14-bit DA chip, but for all hex output/readback API function, 
we use 16-bit as output hex data, 
for example:
iChipData is 16-bit hex data will be used as output data 

    the iChipData will be converted to 14-bit data before output to DA Chip

    Lbyte = iChipData & 0xff;
    Hbyte = iChipData >> 8;
    Hbyte = Hbyte & 0x3f;
