Creating HowTo for creating custom units about engineeringunits HOT 4 OPEN

22122bd - Just relaxed the restrictions on some methods from Internal to public in order for users to better create their customs units

from engineeringunits.

I have started on a Wiki post about creating custom units.
Could you try it out and see if you can get it to work?

Works for me. Obviously the 2nd method doesn't give you the getters and setter methods which I personally prefer using.

These can be added as extensions as well but it is more work. Note also that you have to use two different namespaces if you want to use the same name for the unit enum and the getter, as is the case for regular units..

Using your example, this would look like:

public static class LengthCostUnitExtensions
{
    // New unit
    public static readonly LengthCostUnit EuroPerMeter = new LengthCostUnit(CostUnit.Euro, LengthUnit.Meter);
}

public static class LengthCostExtensions
{
    // New getter
    public static double EuroPerMeter(this LengthCost lengthCost) => lengthCost.As(LengthCostUnitExtensions.EuroPerMeter);

    // New setter method
    public static LengthCost FromEuroPerMeter(double? EuroPerMeter)
    {
        if (!EuroPerMeter.HasValue)
        {
            return null;
        }

        return new LengthCost(EuroPerMeter.Value, LengthCostUnitExtensions.EuroPerMeter);
    }
}

It's not ideal since the getter is now a method instead of a property and the setter has to be called with the extensions namespace:

// ideally LengthCost lc = LengthCost.FromEuroPerMeter(30.0);
LengthCost lc = LengthCostExtensions.FromEuroPerMeter(30.0);

 // ideally Console.WriteLine(lc.EuroPerMeter);
Console.WriteLine(lc.EuroPerMeter());

Btw, was "Costume Units" in the wiki (both title and url) intended or a typo?
