/*This file creates a constructor function for a Google Maps object and adds a drawMap method that uses the properties of the object to add a Google map to the page.  The properties of the object are:*/
/*elementContaining-the containing element for the map*/
/*before-the element to insert the map before*/
/*elementId-id of the scripted element to contain the map*/
/*lat-Latitude of the point for the map to be centred on*/
/*lng-longitude of the point for the map to be centred on*/
/*magnify-zoom level of the map*/
/*markerText-text to be displayed in a marker at the map centre.  To not add this set the property of this to be ''.*/
/*style-if this property is specified inline styles are added to the scripted div containing the map*/
