/**
 * The Slider control creates a horizontal line overlapped by a chevron that can
 * be moved  along this horizontal line.  The line represents a min/max range.
 * The Slider value increases when the chevron is moved to the right and
 * decreases when moved to the left.  When the chevron is released the current
 * position is given via an onSelection callback.
 *
 * The min/max values must be >= 0.  The control width is represented by this
 * positive range.
 *
 * ## Screen:
 * <img src="https://github.com/jmquigley/gadgets/blob/master/images/slider.png" width="50%" />
 *
 * ## Examples:
 *
 * #### Simple slider, range 0 - 100, with tick marks at 0, 25, 50, 75, 100 with snap
 * ```javascript
 * import {Slider} from 'gadgets';
 *
 * <Slider
 *     max={100}
 *     min={0}
 *     onSelection={(val: number) => debug('slider select: %o', val)}
 *     scale={2}
 *     snap
 *     ticks={5}
 * />
 * ```
 *
 * ## API
 * #### Events
 * - `onSelection(val: number)` - When the user releases the slider chevron this
 * callback is invoked and given the index where the chevron "landed"
 *
 * #### Styles
 * - `ui-slider` - The `div` around the whole control (the root)
 * - `ui-slider-bar` - The `div` that makes up the central bar that the chevron
 * will slide over.
 * - `ui-slider-element` - the `div` that represents the draggable chevron
 * - `ui-slider-tick` - when tick marks are displayed on the control, this class
 * is attached to each.  The ticks are a `div` container
 *
 * #### Properties
 * - `max=100 {number}` - The maximum size of the range, counting by 1's
 * - `min=0 {number}` - The starting point for the range
 * - `scale=1 {number}` - A sizing (width) multiplier for the range.  It doens't
 * change the counting range, but just the drawing size.  A scale of 2 with the
 * default min/max would yield a width of 200px, but the range would still be 0-100
 * - `snap=false {boolean}` - When the ticks option is used this will determine
 * if the chevron slider will be forced to fall on one of the tick marks.
 * - `startPosition=0 {number}` - the range start position between min/max
 * - ticks=0 {number}` - A visual number of "stopping" points along the slider
 * These are divided evenly into the range of the slider.  e.g. a setting of 5
 * would show 5 tick marks along the slider.  These positions are also used as a
 * landing point when snap is set to true.
