function DragStart	(	overlay,
		in_point
	)

This is called as a drag of the marker starts.

function GetDependentNodes	(	in_dom_id,
		in_child_nodes
	)

Traverses the DOM tree, and returns an array of all the elements with IDs that contain this element's ID.

Returns:: an array of DOM node objects. These are ones that are directly or indirectly dependent upon this one. The array is flat.

Parameters:

in_dom_id	The DOM ID that will be the basis of what we are looking for. The IDs are written in a way that shows hierarchy.
in_child_nodes	The childnodes to check.

function HideThrobber ( )

Reverses the above.

if ( (typeof(navigator)== 'object'&&typeof(navigator.geolocation)== 'object')||(typeof(google)== 'object'&&typeof(google.gears)== 'object') )

if ( document. getElementById 'advanced_search_mode' )

if ( document. getElementById 'advanced_mapmode' )

function MakeSmallMap	(	in_lat,
		in_lng,
		in_zoom,
		in_disable_multi_zoom
	)

This makes the small map for the basic search. The map does not display any markers or overlays, and just allows the visitor to click anywhere. When they click, they will be either taken to the large, full-page map, or a list.

function ServiceBodyCheckboxChanged ( in_dom_id )

This function is called whenever one of the Service Body checkboxes changes value. If there are dependents, then they are all changed to match this one.

Parameters:

in_dom_id The DOM ID of the checkbox. The IDs are written in a way that shows hierarchy.
