/**
 * Since a lot of sliders already exist, we did not include one by default.
 * However you can easily connect React InstantSearch to an existing one
 * using the [connectRange connector](connectors/connectRange.html).

 * @name RangeSlider
 * @requirements To connect any slider to Algolia, the underlying attribute used must be holding numerical values.
 * @kind widget

 * // Here's an example showing how to connect the AirBnb Rheostat Slider to React InstantSearch
 * // using the range connector. ⚠️ This example only works with the version 2.x of Rheostat.
