v0.2.3

• Add cloneNode helper
  Now, we can clone existing vnode in the context of apply

  import { apply } from 'vue-vnode-helper'
  import cloneNode from 'vue-vnode-helper/clone-node'
  
  export default {
    render (h) {
      return apply(h,
        cloneNode(this.$slots.default[0], { props: { value: 'foo' }}, ['children'])
      )
    }
  }
