* add small dom utility to resolve the dom node from a ref
* use dom() to resolve underlying DOM node
There is probably a better way to do this, the idea is that we apply a
ref to the component. However by default for html components
`yourRef.value` will be the underlying DOM node. However if you pass the
ref to another component, the actual DOM node will be located at
`yourRef.value.$el`.
Fixes: #21
* update changelog
