//	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'
*   disableHiddenCheck - If set to true, then the plugin will assume that charts will never be drawn into a
*           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
*       defaults to false (highlights enabled)

*   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

*                      or expected range of values
*       normalRangeColor - Color to use for the above bar
*       drawNormalOnTop - Draw the normal range above the chart fill color if true
*       defaultPixelsPerValue - Defaults to 3 pixels of width for each value in the chart
*       highlightSpotColor - The color to use for drawing a highlight spot on mouseover - Set to null to disable

 *
 * ```js
 * {
 *     "<someName1>": layer1,
 *     "<someName2>": layer2
 * }
 * ```
 *

 * @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;
 *     }
 * });
 * ```
