Create a new random {@code LongGene} with the given value and the
given range. If the {@code value} isn't within the interval [min, max),
no exception is thrown. In this case the method
{@link LongGene#isValid()} returns {@code false}.

@param allele the value of the gene.
@param min the minimal valid value of this gene (inclusively).
@param max the maximal valid value of this gene (exclusively).
