make the vue components reusable

[vsimko]

This repository should contain vue components for seronet that are reusable in other projects.

Some example how should work:
in package.json:

{
  "dependencies": {
    "seronet-vue-datasheet": "git+https://github.com/seronet-project/seronet-vuejs-datasheet.git",
  }
}

then in mycomponent.vue

<template>
  <DataSheet :data="someDatasheetData"/>
</template>
<script>
import DataSheet from 'seronet-vue-datasheet/DataSheet' // or something similar
// get the `someDatasheetData` from somewhere, e.g. graphql server
</script>

this was just a quick and dirty example, maybe the API could be nicer.
