/* This is a re-usable vue component for rendering a button
    that will probably be sending off ajax requests and need
    to show the loading status by setting the `loading` option.
    This can also be used for initial page load when you don't
    know the action of the button yet by setting
    `loading: true, label: undefined`.

    Sample configuration:

    <loading-button
      :loading="true"
      :label="Hello"
      @click="..."
    />
