Each web site owner must provide their own easily obtainable GOOGLE Maps API Key. Please see here: https://developers.google.com/maps/documentation/javascript/get-api-key.
Settings include the default height and width.

The map is called as follows: {tdocgmap position width=999 height=999 kml='kmlpath'}
Note the path [url] to the kml file must be enclosed in single quotes.

The following position options are available when calling the map.
- print - makes the map 100% in width and 700px in height and overrides other settings.
- left - puts the map to the left and wraps text to the right with 15px margin
- right - puts the map to the right and wraps text to the left with 15px margin
- if none of these options are used, the map is centered with no wrapping of text.

The Source code and notes on its development are shown on the web site.
