//	Implementation Summary
//
//	1. Enforce API surface and semantic compatibility with 1.9.x branch
//	2. Improve the module's maintainability by reducing the storage
//		paths to a single mechanism.
//	3. Use the same single mechanism to support "private" and "user" data.
//	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
//	5. Avoid exposing implementation details on user objects (eg. expando properties)
//	6. Provide a clear path for implementation upgrade to WeakMap in 2014

*
* Usage:
*  $(selector).sparkline(values, options)
*
* If values is undefined or set to 'html' then the data values are read from the specified tag:
*   <p>Sparkline: <span class="sparkline">1,4,6,6,8,5,3,5</span></p>
*   $('.sparkline').sparkline();
* There must be no spaces in the enclosed data set
*
* Otherwise values must be an array of numbers or null values
*    <p>Sparkline: <span id="sparkline1">This text replaced if the browser is compatible</span></p>
*    $('#sparkline1').sparkline([1,4,6,6,8,5,3,5])
*    $('#sparkline2').sparkline([1,4,6,null,null,5,3,5])
*
* Values can also be specified in an HTML comment, or as a values attribute:
*    <p>Sparkline: <span class="sparkline"><!--1,4,6,6,8,5,3,5 --></span></p>
*    <p>Sparkline: <span class="sparkline" values="1,4,6,6,8,5,3,5"></span></p>
*    $('.sparkline').sparkline();
*
* For line charts, x values can also be specified:
*   <p>Sparkline: <span class="sparkline">1:1,2.7:4,3.4:6,5:6,6:8,8.7:5,9:3,10:5</span></p>
*    $('#sparkline1').sparkline([ [1,1], [2.7,4], [3.4,6], [5,6], [6,8], [8.7,5], [9,3], [10,5] ])
*
* By default, options should be passed in as the second argument to the sparkline function:
*   $('.sparkline').sparkline([1,2,3,4], {type: 'bar'})
*
* Options can also be set by passing them on the tag itself.  This feature is disabled by default though
* as there's a slight performance overhead:
*   $('.sparkline').sparkline([1,2,3,4], {enableTagOptions: true})
*   <p>Sparkline: <span class="sparkline" sparkType="bar" sparkBarColor="red">loading</span></p>
* Prefix all options supplied as tag attribute with "spark" (configurable by setting tagOptionsPrefix)
*
* Supported options:
*   lineColor - Color of the line used for the chart
*   fillColor - Color used to fill in the chart - Set to '' or false for a transparent chart

*   chartRangeMinX - Specify the minimum value to use for the X range of the chart - Defaults to the minimum value supplied
*   chartRangeMaxX - Specify the maximum value to use for the X range of the chart - Defaults to the maximum value supplied
*   composite - If true then don't erase any existing chart attached to the tag, but draw
*           another chart over the top - Note that width and height are ignored if an
*           existing chart is detected.

*   enableTagOptions - Whether to check tags for sparkline options
*   tagOptionsPrefix - Prefix used for options supplied as tag attributes - Defaults to 'spark'

*           hidden dom element, avoding a browser reflow
*   disableInteraction - If set to true then all mouseover/click interaction behaviour will be disabled,
*       making the plugin perform much like it did in 1.x
*   disableTooltips - If set to true then tooltips will be disabled - Defaults to false (tooltips enabled)
*   disableHighlight - If set to true then highlighting of selected chart elements on mouseover will be disabled

*   tooltipFormatter  - Optional callback that allows you to override the HTML displayed in the tooltip
*       callback is given arguments of (sparkline, options, fields)
*   tooltipChartTitle - If specified then the tooltip uses the string specified by this setting as a title
*   tooltipFormat - A format string or SPFormat object  (or an array thereof for multiple entries)
*       to control the format of the tooltip
*   tooltipPrefix - A string to prepend to each field displayed in a tooltip
*   tooltipSuffix - A string to append to each field displayed in a tooltip
*   tooltipSkipNull - If true then null values will not have a tooltip displayed (defaults to true)
*   tooltipValueLookups - An object or range map to map field values to tooltip strings
*       (eg. to map -1 to "Lost", 0 to "Draw", and 1 to "Win")
*   numberFormatter - Optional callback for formatting numbers in tooltips
*   numberDigitGroupSep - Character to use for group separator in numbers "1,234" - Defaults to ","
*   numberDecimalMark - Character to use for the decimal point when formatting numbers - Defaults to "."
*   numberDigitGroupCount - Number of digits between group separator - Defaults to 3

 *
 * ```js
 * map.on('click', function(e) {

 *
 * ```js
 * {
 *     "<someName1>": layer1,
 *     "<someName2>": layer2
 * }
 * ```
 *
 * The layer names can contain HTML, which allows you to add additional styling to the items:

 * ```

 * A class for drawing polygon overlays on a map. Extends `Polyline`.
 *
 * Note that points you pass when creating a polygon shouldn't have an additional last point equal to the first one — it's better to filter out such points.
 *
 *
 * @example
 *
 * ```js
 * // create a red polygon from an array of LatLng points
 * var latlngs = [[37, -109.05],[41, -109.03],[41, -102.05],[37, -102.04]];
 *
 * var polygon = L.polygon(latlngs, {color: 'red'}).addTo(map);
 *
 * // zoom the map to the polygon
 * map.fitBounds(polygon.getBounds());
 * ```
 *
 * You can also pass an array of arrays of latlngs, with the first array representing the outer shape and the other arrays representing holes in the outer shape:
 *
 * ```js
 * var latlngs = [
 *   [[37, -109.05],[41, -109.03],[41, -102.05],[37, -102.04]], // outer ring
 *   [[37.29, -108.58],[40.71, -108.58],[40.71, -102.50],[37.29, -102.50]] // hole
 * ];
 * ```
 *
 * Additionally, you can pass a multi-dimensional array to represent a MultiPolygon shape.
 *
 * ```js
 * var latlngs = [
 *   [ // first polygon
 *     [[37, -109.05],[41, -109.03],[41, -102.05],[37, -102.04]], // outer ring

/*
 * @class Popup
 * @inherits DivOverlay
 * @aka L.Popup
 * Used to open popups in certain places of the map. Use [Map.openPopup](#map-openpopup) to
 * open popups while making sure that only one popup is open at one time
 * (recommended for usability), or use [Map.addLayer](#map-addlayer) to open as many as you want.
 *
 * @example
 *
 * If you want to just bind a popup to marker click and then open it, it's really easy:
 *
 * ```js
 * marker.bindPopup(popupContent).openPopup();
 * ```
 * Path overlays like polylines also have a `bindPopup` method.
 * Here's a more complicated way to open a popup on a map:
 *
 * ```js
 * var popup = L.popup()
 * 	.setLatLng(latlng)
 * 	.setContent('<p>Hello world!<br />This is a nice popup.</p>')
 * 	.openOn(map);
 * ```

 * @class GridLayer
 * @inherits Layer
 * @aka L.GridLayer
 *
 * Generic class for handling a tiled grid of HTML elements. This is the base class for all tile layers and replaces `TileLayer.Canvas`.
 * GridLayer can be extended to create a tiled grid of HTML elements like `<canvas>`, `<img>` or `<div>`. GridLayer will handle creating and animating these DOM elements for you.
 *
 *
 * @section Synchronous usage
 * @example
 *
 * To create a custom layer, extend GridLayer and implement the `createTile()` method, which will be passed a `Point` object with the `x`, `y`, and `z` (zoom level) coordinates to draw your tile.
 *
 * ```js
 * var CanvasLayer = L.GridLayer.extend({
 *     createTile: function(coords){
 *         // create a <canvas> element for drawing
 *         var tile = L.DomUtil.create('canvas', 'leaflet-tile');
 *
 *         // setup tile width and height according to the options
 *         var size = this.getTileSize();
 *         tile.width = size.x;
 *         tile.height = size.y;
 *
 *         // get a canvas context and draw something on it using coords.x, coords.y and coords.z
 *         var ctx = tile.getContext('2d');
 *
 *         // return the tile so it can be rendered on screen
 *         return tile;
 *     }
 * });
 * ```
 *
 * @section Asynchronous usage
 * @example
 *
 * Tile creation can also be asynchronous, this is useful when using a third-party drawing library. Once the tile is finished drawing it can be passed to the `done()` callback.
 *
 * ```js
 * var CanvasLayer = L.GridLayer.extend({
 *     createTile: function(coords, done){
 *         var error;
 *
 *         // create a <canvas> element for drawing
 *         var tile = L.DomUtil.create('canvas', 'leaflet-tile');
 *
 *         // setup tile width and height according to the options
 *         var size = this.getTileSize();
 *         tile.width = size.x;
 *         tile.height = size.y;
 *
 *         // draw something asynchronously and pass the tile to the done() callback
 *         setTimeout(function() {
 *             done(error, tile);
 *         }, 1000);
 *
 *         return tile;
 *     }
 * });
 * ```
