+/*
+ * The Highcharts Data plugin is a utility to ease parsing of input sources like
+ * CSV, HTML tables or grid views into basic configuration options for use
+ * directly in the Highcharts constructor.
+ *
+ * Demo: http://jsfiddle.net/highcharts/SnLFj/
+ *
+ * --- OPTIONS ---
+ *
+ * - columns : Array<Array<Mixed>>
+ * A two-dimensional array representing the input data on tabular form. This input can
+ * be used when the data is already parsed, for example from a grid view component.
+ * Each cell can be a string or number. If not switchRowsAndColumns is set, the columns
+ * are interpreted as series. See also the rows option.
+ *
+ * - complete : Function(chartOptions)
+ * The callback that is evaluated when the data is finished loading, optionally from an
+ * external source, and parsed. The first argument passed is a finished chart options
+ * object, containing series and an xAxis with categories if applicable. Thise options
+ * can be extended with additional options and passed directly to the chart constructor.
+ *
+ * - csv : String
+ * A comma delimited string to be parsed. Related options are startRow, endRow, startColumn
+ * and endColumn to delimit what part of the table is used. The lineDelimiter and
+ * itemDelimiter options define the CSV delimiter formats.
+ *
+ * - endColumn : Integer
+ * In tabular input data, the first row (indexed by 0) to use. Defaults to the last
+ * column containing data.
+ *
+ * - endRow : Integer
+ * In tabular input data, the last row (indexed by 0) to use. Defaults to the last row
+ * containing data.
+ *
+ * - googleSpreadsheetKey : String
+ * A Google Spreadsheet key. See https://developers.google.com/gdata/samples/spreadsheet_sample
+ * for general information on GS.
+ *
+ * - googleSpreadsheetWorksheet : String
+ * The Google Spreadsheet worksheet. The available id's can be read from
+ * https://spreadsheets.google.com/feeds/worksheets/{key}/public/basic
+ *
+ * - itemDelimiter : String
+ * Item or cell delimiter for parsing CSV. Defaults to ",".
+ *
+ * - lineDelimiter : String
+ * Line delimiter for parsing CSV. Defaults to "\n".
+ *
+ * - parsed : Function
+ * A callback function to access the parsed columns, the two-dimentional input data
+ * array directly, before they are interpreted into series data and categories.
+ *
+ * - parseDate : Function
+ * A callback function to parse string representations of dates into JavaScript timestamps.
+ * Return an integer on success.
+ *
+ * - rows : Array<Array<Mixed>>
+ * The same as the columns input option, but defining rows intead of columns.
+ *
+ * - startColumn : Integer
+ * In tabular input data, the first column (indexed by 0) to use.
+ *
+ * - startRow : Integer
+ * In tabular input data, the first row (indexed by 0) to use.
+ *
+ * - table : String|HTMLElement
+ * A HTML table or the id of such to be parsed as input data. Related options ara startRow,
+ * endRow, startColumn and endColumn to delimit what part of the table is used.
