3.1.0

-----

* [!] Major refactoring. Broken into `SliderBase`, `ClickableRail`, and

`SliderValueRange` classes, and `Y.Slider` is the product of

`Y.Base.build(…)` of these. `SliderBase` is responsible for rendering the UI

and broadcasting `slideStart`, `slideEnd`, and `thumbMove` events.

`ClickableRail` adds support for clicking on the `rail` to move the `thumb`.

`SliderValueRange` adds support for `min`, `max`, and `value` attributes.

Values are integers ranging from 0 to 100 by default. `Base.build()` in

different value algorithms or extensions to specialize from `SliderBase`.

* [!] `railSize` attribute renamed to `length`.

* [!] `maxGutter` and `minGutter` attributes removed. Use CSS and/or apply

manually via `slider._dd.con.set('gutter', …);`.

* [!] `rail`, `thumb`, `thumbImg` `Node` attributes removed, as well as

`HTML_PARSER` support. Progressive enhancement stems from a value source,

not a markup source. Various progressive enhancement extensions will arrive

in future versions.

* Sam skin updated and 7 new skins added (`sam-dark`, `round`, `round-dark`,

`capsule`, `capsule-dark`, `audio`, `audio-light`).

* New markup and CSS structure including separate shadow image (set to same

image as thumb, positioned via CSS ala sprite.

* Thumb placement method changed from `setXY()` and `DD` positioning methods

to simpler `setStyle('left', x)` or `top` for vertical Sliders. Allows

rendering and modifying in hidden containers without the need to `syncUI()`

when making visible. Still recommended to call `syncUI()` if rendered off

DOM, but may not be necessary if using Sam skin. YMMV.

3.0.0

-----

* Removed noop `_setValueFn()` and the setter config for the `value`

attribute.

* Renamed static protected `AXIS_KEYS` to `_AXIS_KEYS`.

* Renamed `_defUpdateValueFromDD` to `_defThumbDragFn` per naming conventions.

* Added `_convertOffsetToValue` to mirror `_convertValueToOffset`.

----------

* Renamed the `valueSet` custom event to `positionThumb` and rejiggered the

logic of the default function and support methods.

* renamed `_defSyncUI` to `_defSyncFn` for library nomenclature consistency.

* Added protected `_convertValueToOffset` to help position the thumb.

* Set `bubble: false` on the `DD.Drag` instance.
