the class Builder method targetDistance.

     * a given target.
     *
     * @param constraints Current NameConstraints; if null,
     *        then caller must verify NameConstraints
     *        independently, realizing that this certificate
     *        may not actually lead to the target at all.
     * @param cert Candidate certificate for chain
     * @param target GeneralNameInterface name of target
     * @return distance from this certificate to target:
     * <ul>
     * <li>-1 means certificate could be CA for target, but
     *     there are no NameConstraints limiting how close
     * <li> 0 means certificate subject or subjectAltName
     *      matches target
     * <li> 1 means certificate is permitted to be CA for
     *      target.
     * <li> 2 means certificate is permitted to be CA for
     *      parent of target.
     * <li>&gt;0 in general, means certificate is permitted
     *     to be a CA for this distance higher in the naming
     *     hierarchy than the target, plus 1.
     * </ul>
     * <p>Note that the subject and/or subjectAltName of the
     * candidate cert does not have to be an ancestor of the
     * target in order to be a CA that can issue a certificate to
     * the target. In these cases, the target distance is calculated
     * by inspecting the NameConstraints extension in the candidate
     * certificate. For example, suppose the target is an X.500 DN with
     * a value of "CN=mullan,OU=ireland,O=sun,C=us" and the
     * NameConstraints extension in the candidate certificate
     * includes a permitted component of "O=sun,C=us", which implies
     * that the candidate certificate is allowed to issue certs in
     * the "O=sun,C=us" namespace. The target distance is 3
     * ((distance of permitted NC from target) + 1).
     * The (+1) is added to distinguish the result from the case
     * which returns (0).
     * @throws IOException if certificate does not get closer
