Hi all,

The [CoolProp.jl](https://github.com/CoolProp/CoolProp.jl) wrapper for the [CoolProp](http://www.coolprop.org/) fluids properties library has been around for a while, but now the package is registered and installable from the General repository. I’d like to highlight a new feature, which is support for Units, e.g. to get the enthalpy at 20°c and 50 % relative humidity for humid air:

```julia
using CoolProp
using Unitful: °C, Pa

HAPropsSI("H", "Tdb", 20°C, "RH", 0.5, "P", 101325Pa)
38622.83892391293 J kg⁻¹

```

Note that I am not involved with the project, all the hard work was done by the CoolProp developers, I just updated the package for modern Julia because I use it in my classes.
