Not possible to get and set selected value of ChoiceGroup

[WillemJann]

For the ChoiceGroup component there is no model defined. It is therefore not possible to set the intial selected value, retrieve the selected value and update the selected value.

Suggested syntax:

<ChoiceGroup v-model="selectedOption" :options="options" />

Alternative (similar to CheckBox):

<ChoiceGroup v-for="item in items"
          :key="item.index"
          :selected="selection.indexOf(item.index) > -1"
          @input="onSelect(item)">
      {{ item.text }}
</ChoiceGroup>

An advantage of the syntax with slots is that in the for loop extra content (e.g. an icon) can be added per individual choice group item.
