From 39b21faa5b53e11d3aedf5721d8fc620b414f6f4 Mon Sep 17 00:00:00 2001
From: Braks <78412429+bcakmakoglu@users.noreply.github.com>
Date: Sat, 20 Nov 2021 22:10:25 +0100
Subject: [PATCH] refactor(types)!: Remove elements prop, change
 EdgeTypes/NodeTypes prop to string[]

* no more elements prop - v-model instead!
* Instead of passing an object map to components just pass in an array of strings as nodeTypes/edgeTypes object
* the string name will either be resolved to a dynamic component with :is="type" or a slot with the type-name
* update all examples
