// AddSparkline provides a function to add sparklines to the worksheet by
// given formatting options. Sparklines are small charts that fit in a single
// cell and are used to show trends in data. Sparklines are a feature of Excel
// 2010 and later only. You can write them to an XLSX file that can be read by
// Excel 2007 but they won't be displayed. For example, add a grouped
// sparkline. Changes are applied to all three:
//
// err := f.AddSparkline("Sheet1", &excelize.SparklineOption{
// Location: []string{"A1", "A2", "A3"},
// Range: []string{"Sheet2!A1:J1", "Sheet2!A2:J2", "Sheet2!A3:J3"},
// Markers: true,
// })
//
// The following shows the formatting options of sparkline supported by excelize:
//
// Parameter | Description
// -----------+--------------------------------------------
// Location | Required, must have the same number with 'Range' parameter
