fed41d4518 First implementation of critical point solver (much slower than on windows?) 
``` C++
    std::vector<std::string> names; names.push_back("Methane"); names.push_back("H2S");
    shared_ptr<CoolProp::HelmholtzEOSMixtureBackend> mix(new CoolProp::HelmholtzEOSMixtureBackend(names));
    mix->specify_phase(iphase_gas);
    std::vector<CoolPropDbl> z(2,0);
    for (double x0 = 0.01; x0 < 0.5; x0 += 0.01)
    {
        z[0] = x0; z[1] = 1-x0;
        mix->set_mole_fractions(z);
        std::vector<CoolProp::SimpleState> critpts = mix->find_all_critical_points();
        int rr = 4;
    }
```
