 *
 * The Ignite UI Slider allows selection in a given range by moving the thumb along the track. The track
 * can be defined as continuous or stepped, and you can choose between single and range slider types.
 *
 * Example:
 * ```html
 * <igx-slider id="slider"
 *            [minValue]="0" [maxValue]="100"
 *            [continuous]=true [(ngModel)]="volume">
 * </igx-slider>
 * ```
