// This creates a Google My Map from a Google Spreadsheet using CSV as the data
// exchange. The first line of the spreadsheet must include a "latitude" and

// and <description>. Any other column heading is used as an
// <ExtendedData>/<Data> item. NOTE: the My Maps UI does not show the
// ExtendedData/Data fields, but these are used for Maps Data API attribute
// search and are available in exported KML: to view in Google Earth.
