Quality values

When the application asks you for a quality value it expects to receive either,

1. A name of a quality bit pattern,

        Name      Bit pattern        Name      Bit pattern
    
        GOOD      00000000           PATCHED   01000000
        BAD       00000010           ARITH     00000100
        MISSING   00000001           IGNORE    10000000
   

2. A binary number, up to 8 bits long. This is read in as a character string, and converted to a numeric value later.

   The binary number does not HAVE to be 8 bits long i.e.

                      11 = 00000011
