2c64bdaadf Add chemical potential as abstract state method 
For example:

```
auto fluids = strsplit("Methane&Ethane", '&');
auto x = { 0.6,0.4 };

shared_ptr<CoolProp::AbstractState> RP(CoolProp::AbstractState::factory("HEOS", fluids));
RP->set_mole_fractions(x);
RP->update(PT_INPUTS, 101325, 300);
auto mu1 = RP->chemical_potential(0);

RP.reset(CoolProp::AbstractState::factory("REFPROP", fluids));
RP->set_mole_fractions(x);
RP->update(PT_INPUTS, 101325, 300);
auto mu2 = RP->chemical_potential(0);
```

1068b724c3 CoolPropDbl 
Introduce CoolPropDbl to replace long doubles. This may help to overcome
possible portability problems, and test for efficiency and precision.
