		//		DataPresentation
		//
		//		A widget that connects to a data store in a simple manner,
		//      and also provides some additional convenience mechanisms
		//      for connecting to common data sources without needing to
		//      explicitly construct a Dojo data store. The widget can then
		//      present the data in several forms: as a graphical chart,
		//      as a tabular grid, or as display panels presenting meta-data
		//      (title, creation information, etc) from the data. The
		//      widget can also create and manage several of these forms
		//      in one simple construction.
		//
		//      Note: this is a first experimental draft and any/all details
		//      are subject to substantial change in later drafts.
		//
		//	example:
		//
		//	 	var pres = new dojox.data.DataPresentation("myChartNode", {
		//	 		type: "chart",
		//	 		url: "/data/mydata",
		//          gridNode: "myGridNode"
		//	 	});
		//
		//	properties:
		//
		//  store: Object
		//      Dojo data store used to supply data to be presented. This may
		//      be supplied on construction or created implicitly based on
		//      other construction parameters ('data', 'url').
		//
		//  query: String
		//      Query to apply to the Dojo data store used to supply data to
		//      be presented.
		//
		//  queryOptions: String
		//      Query options to apply to the Dojo data store used to supply
		//      data to be presented.
		//
		//  data: Object
		//      Data to be presented. If supplied on construction this property
		//      will override any value supplied for the 'store' property.
		//
		//  url: String
		//      URL to fetch data from in JSON format. If supplied on
		//      construction this property will override any values supplied
		//      for the 'store' and/or 'data' properties. Note that the data
		//      can also be comment-filtered JSON, although this will trigger
		//      a warning message in the console unless djConfig.useCommentedJson
		//      has been set to true.
		//
		//  urlContent: Object
		//      Content to be passed to the URL when fetching data. If a URL has
		//      not been supplied, this value is ignored.
		//
		//  urlError: function
		//      A function to be called if an error is encountered when fetching
		//      data from the supplied URL. This function will be supplied with
		//      two parameters exactly as the error function supplied to the
		//      dojo.xhrGet function. This function may be called multiple times
		//      if a refresh interval has been supplied.
		//
		//  refreshInterval: Number
		//      the time interval in milliseconds after which the data supplied
		//      via the 'data' property or fetched from a URL via the 'url'
		//      property should be regularly refreshed. This property is
		//      ignored if neither the 'data' nor 'url' property has been
		//      supplied. If the refresh interval is zero, no regular refresh is done.
		//
		//  refreshIntervalPending:
		//      the JavaScript set interval currently in progress, if any
		//
		//  series: Array
		//      an array of objects describing the data series to be included
		//      in the data presentation. Each object may contain the
		//      following fields:
		//			datapoints: the name of the field from the source data which
		//				contains an array of the data points for this data series.
		//				If not supplied, the source data is assumed to be an array
		//				of data points to be used.
		//			field: the name of the field within each data point which
		//				contains the data for this data series. If not supplied,
		//				each data point is assumed to be the value for the series.
		//      	name: a name for the series, used in the legend and grid headings
		//          namefield: the name of the field from the source data which
		//              contains the name the series, used in the legend and grid
		//              headings. If both name and namefield are supplied, name takes
		//              precedence. If neither are supplied, a default name is used.
		//			chart: true if the series should be included in a chart presentation (default: true)
		//          charttype: the type of presentation of the series in the chart, which can be
		//				"range", "line", "bar" (default: "bar")
		//          linestyle: the stroke style for lines (if applicable) (default: "Solid")
		//          axis: the dependant axis to which the series will be attached in the chart,
		//              which can be "primary" or "secondary"
		//			grid: true if the series should be included in a data grid presentation (default: true)
		//			gridformatter: an optional formatter to use for this series in the data grid
		//
		//      a call-back function may alternatively be supplied. The function takes
		//      a single parameter, which will be the data (from the 'data' field or
		//      loaded from the value in the 'url' field), and should return the array
		//      of objects describing the data series to be included in the data
		//      presentation. This enables the series structures to be built dynamically
		//      after data load, and rebuilt if necessary on data refresh. The call-back
		//      function will be called each time new data is set, loaded or refreshed.
		//      A call-back function cannot be used if the data is supplied directly
		//      from a Dojo data store.
		//
		//  type: String
		//      the type of presentation to be applied at the DOM attach point.
		//      This can be 'chart', 'legend', 'grid', 'title', 'footer'. The
		//      default type is 'chart'.
		type: "chart",

		//  chartType: String
		//      the type of chart to display. This can be 'clusteredbars',

		chartType: "clusteredBars",
		//
		//  reverse: Boolean
		//      true if the chart independant axis should be reversed.
		reverse: false,
		//
		//  animate: Object
		//      if an object is supplied, then the chart bars or columns will animate
		//      into place. If the object contains a field 'duration' then the value
		//      supplied is the duration of the animation in milliseconds, otherwise
		//      a default duration is used. A boolean value true can alternatively be
		//      supplied to enable animation with the default duration.
		//      The default is null (no animation).
		animate: null,
		//
		//  labelMod: Integer
		//      the frequency of label annotations to be included on the
		//      independent axis. 1=every label. 0=no labels. The default is 1.
		labelMod: 1,
		//
		//  tooltip: String | Function
		//      a string pattern defining the tooltip text to be applied to chart
		//      data points, or a function which takes a single parameter and returns
		//      the tooltip text to be applied to chart data points. The string pattern
		//      will have the following substitutions applied:
		//       {0} - the type of chart element ('bar', 'surface', etc)
		//       {1} - the name of the data series
		//       {2} - the independent axis value at the tooltip data point
		//       {3} - the series value at the tooltip data point point
		//      The function, if supplied, will receive a single parameter exactly
		//      as per the dojox.charting.action2D.Tooltip class. The default value
		//      is to apply the default tooltip as defined by the
		//      dojox.charting.action2D.Tooltip class.
		//
		//  legendHorizontal: Boolean | Number
		//      true if the legend should be rendered horizontally, or a number if
		//      the legend should be rendered as horizontal rows with that number of
		//      items in each row, or false if the legend should be rendered
		//      vertically (same as specifying 1). The default is true (legend
		//      rendered horizontally).
