Access to the global tariff catalogue.

If tcat_ is 0, the function allocates a new tariff catalogue. This is done in a fairly thread-safe way:

          tcat()
          {
              // Seems that nobody has initialized yet:
              // create a tariff catalogue.
              if (0 == tcat_) {
                  TariffCatalogue* tmp = new TariffCatalogue;
                  // If the tcat pointer is still 0, set it.
                  // Note: this is the thread critical statement.
                  if (0 == tcat_) tcat_ = tmp;
                  // Somebody else has initialized in the meantime:
                  // use its tcat pointer.
                  else delete tmp;
              }
              return *tcat_;
          }

There is only one way how applications can make ensure absolute thread safety: call the member before any threads are created.

Returns:

The global tariff catalogue instance.
