public static BitChromosome of(final int length) {
		return of(length, DEFAULT_PROBABILITY);
	}
Constructing a new BitChromosome with the given {@code length} and
randomly set bits. The TRUEs and FALSE in the {@code Chromosome} are
equally distributed with one-probability of 0.5.

@param length Length of the BitChromosome.
@return a new {@code BitChromosome} with the given parameter
@throws NegativeArraySizeException if the {@code length} is smaller
        than one.
