/**
 * Implements an equals method to compare this instance to other objects.
 * Two instances are considered iff they are both of the same type and their
 * members are equal. That also means that members of both experiments can be
 * {@code null}, as long as the specific member is {@code null} for both instances
 * and not just one.//  w  ww.j a va2s.  c o m
 *
 * However some tests might need two instances to be equal in all but a few attributes, for example
 * two experiments can be equal except for their {@code modificationTime}.
 *
 * In that case you can specify the fields to be excluded from the equality tests by
 * setting the {@link SerializationStrategy} accordingly.
 *
 * Note that this slightly breaks the contract with the consistency of equals and hashCode!
 *
 * @param other another object
 * @return true iff both are objects are of the same type and all but their excluded member variables are equal.
