/**
* # Data Filter Element
* A fast and customizable polymer component for filtering arrays.
*
* ### Features
* - Automatically detect Attribute types from the `data` array.
* - Token based filtering of attributes
* - Flattens `data` for easy viewing as table
* - Customizable filter components
* - Client side filtering of large arrays
* - Supports Manual/Auto selection of rows
* - If `Auto` selected, supports configurable selection Modes
* - Top - select top `x%` of rows
* - Random - selection random `x%` of rows
*
* ### Types of Filters
*
* Attribute Type | Component | Component url
* ---------------|-----------|--------------
* Categorical | `paper-tags` | [webcomponents.org](https://www.webcomponents.org/element/PolymerEl/paper-tags)
* Numerical | `paper-rangle-slider` | [webcomponents.org](https://www.webcomponents.org/element/IftachSadeh/paper-range-slider)
* Boolean | `paper-toggle-button` | [webcomponents.org](https://www.webcomponents.org/element/@polymer/paper-toggle-button)
*
* ### Adding a data filter component to an application
* In typical use, just add `<data-filter>` to the HTML page:
*
* <data-filter data="[]"></data-filter>
*
* @customElement
* @polymer
* @demo demo/index.html
