   * Safety coefficient based on an integration error. It computes an integration error based on the difference of the norm of the acceleration. A maximal value is set by the user. Practically, the safety coefficient will only be lower than this user parameter for highly dynamic situations, such as impact.   * Safety coefficient based on an integration error.
