// Purpose  : BrainGnat.Google - A series of Google API-specific extensions for use with BrainGnat.
//*************************************************************************************

// 0.3.0
// Google               - New namespace for Google mashups
// Google.map           - New namespace for Google maps mashups
// Google.map.load(elem)- Loads elem (defined by css selecor). If selector is for more than one element, only selects the first one.
// Google.map.addMarker(latlng,info) - Loads point defined by latlng and adds a marker. If info has a value, puts it in an info bubble.
// Google.map.addMarkerByAddress(address,info) - loads point defined by address and adds a marker. If info has a value, puts it in a info bubble.
// Google.map.setCenterByAddress(address, zoom) - sets the center of map to a provided address.
// Google.map.loadFromHCard(card, map, zoom) - Loads a map, gets the address from an hcard and sets a marker there, and if zoom is provided, zooms to that level.
// 0.3.1
// Google.map.addDirections(elem) - Sets elem as a direction pane for a google map
// Google.map.getDirections(to, from) - Inserts into directions pane created through .addDirections() a series of directions to address "to" from address "from".
// 0.3.2
// Some Google.map code polishing
// 0.4.0
// BrainGnat.Google has been spun out into a separate script that must be included in projects that make use of it.
// Syntax is the same, it merely exists as an extension now.
