Returns {@code true} if this BigInteger is probably prime,
{@code false} if it's definitely composite. If
{@code certainty} is ≤ 0, {@code true} is
returned.
@param certainty a measure of the uncertainty that the caller is
willing to tolerate: if the call returns {@code true}
the probability that this BigInteger is prime exceeds
(1 - 1/2<sup>{@code certainty}</sup>). The execution time of
this method is proportional to the value of this parameter.
@return {@code true} if this BigInteger is probably prime,
{@code false} if it's definitely composite.
