fread() the file with PRECISION 'bit4=>uint8'. The result will be an unsigned 
numeric array. If you need to convert the unsigned numeric array to the 
traditional equivalent characters, index ['0':'9','A':'F'] by the
(the numeric array + 1). The +1 compensates for the fact that Matlab indexing 
starts at 1, not a 0.
