/**
 * @brief The class that implements an event random vector, i.e. a
 *        composite random vector built upon a boolean function which
 *        is described by a threshold and a comparison operator. The
 *        antecedent of the event must be a "classical" composite random
 *        vector in the context of OpenTURNS.
