    Make it faster
    
    Short-circuiting currency::round() yields some improvement:
    
    $wine ./lmi_cli_shared.exe --accept --data_path=/opt/lmi/data --selftest
    Test speed:
      naic, no solve      : 9.810e-02 s mean;     96952 us least of  11 runs
      naic, specamt solve : 1.722e-01 s mean;    171329 us least of   6 runs
      naic, ee prem solve : 1.571e-01 s mean;    156184 us least of   7 runs
      finra, no solve     : 2.748e-02 s mean;     25921 us least of  37 runs
      finra, specamt solve: 9.320e-02 s mean;     91937 us least of  11 runs
      finra, ee prem solve: 8.576e-02 s mean;     84584 us least of  12 runs
