`paper-slider` allows user to select a value from a range of values by
moving the slider thumb.  The interactive nature of the slider makes it a 
great choice for settings that reflect intensity levels, such as volume, 
brightness, or color saturation.

Example:

    <paper-slider></paper-slider>

Use `min` and `max` to specify the slider range.  Default is 0 to 100.

Example:

    <paper-slider min="10" max="200" value="110"></paper-slider>

Styling slider:

To change the slider progress bar color:

    paper-slider::shadow #sliderBar::shadow #activeProgress {
      background-color: #0f9d58;
    }

To change the slider knob color:

    paper-slider::shadow #sliderKnobInner {
      background-color: #0f9d58;
    }

To change the slider pin color:

    paper-slider::shadow #sliderKnobInner::before {
      background-color: #0f9d58;
    }

To change the slider pin's value:

    paper-slider::shadow #sliderKnobInner::after {
      color: #0f9d58
    }

To change the slider secondary progress bar color:

    paper-slider::shadow #sliderBar::shadow #secondaryProgress {
      background-color: #0f9d58;
    }
