integerToBoolean converts a scalar positive integer (or zero) to its
binary representation as list of logicals.
booleanFunctionVector returns the boolean vector of result values of
f, given a boolean function f.
numberOfDifferentBits given two lists of booleans of equal length,
returns the number of differing bits.
makeBooleanFitnessFunction given a boolean target function, returns
a fitness function that returns the number of different places in the output
of a given boolean function and the target function.
