This class can display maps using Google Maps API v3.

It can generate HTML with JavaScript to show a map of a given region of the world using Google Maps.

The class provides means to configure several options of presentation of the maps like the geographic position from explicit coordinates or using geocoding to find the location of an address or a device location sensor, map type, zoom level, position and styles of the controls, custom markers, etc..

1. OVERVIEW. 
-----------------------------------------------------------

This class can be used to generate dynamic maps of different types, sizes, UI control 
sets and to place customizable markers and info windows attached to markers on it.
It uses Google Maps API v3 service to generate Javascript and HTML output to display 
the map in browser's window. It also implements Google Maps Geocoding functionality to 
retrieve longitude and latitude coordinates from human readable address strings.
In the browsers, which support W3C Geolocation API, it can read Geolocation sensor 
(e.g. GPS) data and place a marker and/or set map's center position using that data.

5. THE MARKER OPTIONS ARRAY.
-----------------------------------------------------------

The marker's options array may contain the following keys:

string animation 
Which animation to play when marker is added to a map.
If set, the possible values are:
MapBuilder::ANIMATION_BOUNCE
MapBuilder::ANIMATION_DROP

bool clickable 
If true, the marker receives mouse and touch events. Default value is true.

string cursor 
Mouse cursor to show on hover.

bool draggable
If true, the marker can be dragged. Default value is false.

bool flat 
If true, the marker shadow will not be displayed.

string icon 
Custom icon's URL for the marker.

string defColor
When the custom icon is not set or empty, a default baloon marker could be shown using specified background color. 

string defSymbol 
When the custom icon is not set or empty, a default baloon marker could be shown using specified symbol (e.g. number or letter) in the center. 
        
bool optimized
Optimization renders many markers as a single static element. Optimized rendering is enabled by default. Disable optimized rendering for animated GIFs or PNGs, or when each marker must be rendered as a separate DOM element (advanced usage only).

bool raiseOnDrag 
If false, disables raising and lowering the marker on drag. This option is true by default.

string shadow 
The URL of the shadow image of the marker.
   
string title 
Marker rollover text.

bool visible
If false, the marker will not be visible.
 
int zIndex 
All markers are displayed on the map in order of their zIndex, with higher values displaying in front of markers with lower values. By default, markers are displayed according to their vertical position on screen, with lower markers appearing in front of markers further up the screen.

string html
Content to display in the info window when clicking on the marker. This can be an HTML element, a plain-text string, or a string containing HTML. The InfoWindow will be sized according to the content. To set an explicit size for the content, set content to be a HTML element with that size.
 
int infoMaxWidth 
Maximum width of the info window, regardless of content's width. 

bool infoDisableAutoPan 
Disable auto-pan on open. By default, the info window will pan the map so that it is fully visible when it opens.

int infoZIndex 
All info windows are displayed on the map in order of their zIndex, with higher values displaying in front of info windows with lower values. By default, info winodws are displayed according to their latitude, with info windows of lower latitudes appearing in front of info windows at higher latitudes. Info windows are always displayed in front of markers.

bool infoCloseOthers = false
Close other opened info windows before opening the entire info window.

Note: Almost all values in options array are set to null by default which indicate the corresponding parameters have not been set yet.
