The file config.h contains two system specific specifications used in
performing logical operations on floating pointer numbers.

The first is LOGIC_BITS.  This is the number of bits of the stored mantissa
to use.  This need not be more than the actual number in the double type.
The small programme mant.c should calculate the actual number of bits of
stored mantissa in a double.

The second is logic_t.  This is the signed integer type to use.  This
should be large enough to store LOGIC_BITS of stored mantissa plus the
implied one plus the sign bit.  That is; it must be at least LOGIC_BITS+2
bits in size.

The distribution values of "52" and "long long" are for an IEEE double
precision double and a 64 bit long long.  Values of "30" and "long"
might be better.
