*
* 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 teh 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 tagOptionPrefix)
*
* 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
* width - Width of the chart - Defaults to 3 times the number of values in pixels
* height - Height of the chart - Defaults to the height of the containing element
* chartRangeMin - Specify the minimum value to use for the Y range of the chart - Defaults to the minimum value supplied
* chartRangeMax - Specify the maximum value to use for the Y range of the chart - Defaults to the maximum value supplied
* chartRangeClip - Clip out of range values to the max/min specified by chartRangeMin and chartRangeMax
* 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.
* tagValuesAttribute - Name of tag attribute to check for data values - Defaults to 'values'
* enableTagOptions - Whether to check tags for sparkline options
* tagOptionPrefix - 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

* tooltipOffsetY - How many pixels away from the mouse pointer to render the tooltip on the r axis
* 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)

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

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

* @class Control.Layers
* @aka L.Control.Layers
* @inherits Control
*
* The layers control gives users the ability to switch between different base layers and switch overlays on/off (check out the [detailed example](http://leafletjs.com/examples/layers-control.html)). Extends `Control`.
*
* @example
*
* ```js
* var baseLayers = {
* "Mapbox": mapbox,
* "OpenStreetMap": osm
* };
*
* var overlays = {
* "Marker": marker,
* "Roads": roadsLayer
* };
*
* L.control.layers(baseLayers, overlays).addTo(map);
* ```
*
* The `baseLayers` and `overlays` parameters are object literals with layer names as keys and `Layer` objects as values:
*
* ```js
* {
* "<someName1>": layer1,
* "<someName2>": layer2
* }
* ```
*
* The layer names can contain HTML, which allows you to add additional styling to the items:
*
* ```js
* {"<img src='my-layer-icon' /> <span class='my-layer-item'>My Layer</span>": myLayer}
* ```
