I want the variable key automated in herman-add mixins

[mirisuzanne]

When we add a variable to the output map, we have to set a key that Herman will look for, as well as providing the variable:

@include herman-add('my-colors', $my-colors);

It would be great to automate the key, and only pass in the value – but not simple in Sass. We can't easily get one (key or value) based on the other.

I have a long-shot idea for this, using the Sass compilation-order to automate keys - rather than the object name. It feels a bit fragile to me at first, but theoretically, Sass and Herman should always compile the documents in the same order – so they should both be able to determine the proper key reliably.
