Responsive gutters create NaN Values

[X-Tender]

Compile with responsive-gutter=true from the responsive-gutter-fix pull request and look at the output.

the Issue could be somewhere in the getGutterValueMethod.
You do:

value = settings.responsiveGutter ? (value / Math.floor(referenceWidth)) * 100 : value;

But thereferenceWidth is NaN when it comes in.

@X-Tender as mentioned in the docs you need to have a viewport property set in the default grid settings

To make this feature work you have to set a viewport context even in your default settings of the grid.

Add viewport: 375px; for example and try again. This value is required to calculate relative gutter values.

Maybe adding a default viewport value for the base viewport could help here.

Ok shame on me, I just played around with the properties.
Myb a default value or a warning when using this without a viewport in the base view (or both) lik
Warning! You didn't set a viewport for the Default view, fallback to 375px

Seems appropriate to me.
