A way to create persistent fragments
npm install uwire 
A way to create persistent "_wired_" fragments that can be moved around when diffed through _µdomdiff_.
``js
import {diffable, persistent} from 'uwire';
const wire = persistent(fragment);
diffable(wire, 1); // repopulate all nodes, if gone, returns the fragment
diffable(wire, 0); // return the initial fragment firstChild
diffable(wire, -0); // return the initial fragment lastChild
diffable(wire, -1); // remove all nodes and return the firstChild
`
If the fragment has only one child node, the diffable will always return that child node instead, making it a no-op.
It's like attaching, via strings (_wires_), the behavior of a _fragment_ that cannot be used to obtain the same result.
A _wire_ is not really a fragment per se, but it carries with it all it's needed to reuse, move, remove, re-append, such fragment.
