Detailed Description

A DDValue std::maps a std::vector of DDValuePair (std::string,double) to a name. Names of DDValues are stored transiently. Furthermore, an ID is assigned std::mapping to the name. Use DDValue::setEvalState(true) to indicate whether the double numbers stored in the DDValuePair make sense, otherwise an exception will be thrown when trying to get access to these values via DDValue::doubles() or DDValue::operator[].
