/**
* @name MarkerClustererPlus for Google Maps V3
* @version 2.0.9 [February 20, 2012]
* @author Gary Little
* @fileoverview
* The library creates and manages per-zoom-level clusters for large amounts of markers.
*
* This is an enhanced V3 implementation of the
* V2 MarkerClusterer by Xiaoxi Wu. It is based on the
* V3 MarkerClusterer port by Luke Mahe. MarkerClustererPlus was created by Gary Little.
*
* v2.0 release: MarkerClustererPlus v2.0 is backward compatible with MarkerClusterer v1.0. It
* adds support for the ignoreHidden, title, printable,
* batchSizeIE, and calculator properties as well as support for
* four more events. It also allows greater control over the styling of the text that appears
* on the cluster marker. The documentation has been significantly improved and the overall
* code has been simplified and polished. Very large numbers of markers can now be managed
* without causing Javascript timeout errors on Internet Explorer. Note that the name of the
* clusterclick event has been deprecated. The new name is click,
* so please change your application code now.

/**
* @name ClusterIconStyle
* @class This class represents the object for values in the styles array passed
* to the {@link MarkerClusterer} constructor. The element in this array that is used to
* style the cluster icon is determined by calling the calculator function.
*
* @property {string} url The URL of the cluster icon image file. Required.
* @property {number} height The height (in pixels) of the cluster icon. Required.
* @property {number} width The width (in pixels) of the cluster icon. Required.
* @property {Array} [anchor] The anchor position (in pixels) of the label text to be shown on
* the cluster icon, relative to the top left corner of the icon.
* The format is [yoffset, xoffset]. The yoffset must be positive
* and less than height and the xoffset must be positive and less
* than width. The default is to anchor the label text so that it is centered
* on the icon.
* @property {Array} [anchorIcon] The anchor position (in pixels) of the cluster icon. This is the
* spot on the cluster icon that is to be aligned with the cluster position. The format is
* [yoffset, xoffset] where yoffset increases as you go down and
* xoffset increases to the right. The default anchor position is the center of the
* cluster icon.
* @property {string} [textColor="black"] The color of the label text shown on the
* cluster icon.
* @property {number} [textSize=11] The size (in pixels) of the label text shown on the
* cluster icon.
* @property {number} [textDecoration="none"] The value of the CSS text-decoration
* property for the label text shown on the cluster icon.
* @property {number} [fontWeight="bold"] The value of the CSS font-weight
* property for the label text shown on the cluster icon.
* @property {number} [fontStyle="normal"] The value of the CSS font-style
* property for the label text shown on the cluster icon.
* @property {number} [fontFamily="Arial,sans-serif"] The value of the CSS font-family
* property for the label text shown on the cluster icon.
* @property {string} [backgroundPosition="0 0"] The position of the cluster icon image
* within the image defined by url. The format is "xpos ypos"
* (the same format as for the CSS background-position property). You must set
* this property appropriately when the image defined by url represents a sprite
* containing multiple images.

/**
* @name MarkerClustererOptions
* @class This class represents the optional parameter passed to

* @property {number} [gridSize=60] The grid size of a cluster in pixels. The grid is a square.
* @property {number} [maxZoom=null] The maximum zoom level at which clustering is enabled or
* null if clustering is to be enabled at all zoom levels.
* @property {boolean} [zoomOnClick=true] Whether to zoom the map when a cluster marker is
* clicked. You may want to set this to false if you have installed a handler
* for the click event and it deals with zooming on its own.
* @property {boolean} [averageCenter=false] Whether the position of a cluster marker should be
* the average position of all markers in the cluster. If set to false, the
* cluster marker is positioned at the location of the first marker added to the cluster.
* @property {number} [minimumClusterSize=2] The minimum number of markers needed in a cluster
* before the markers are hidden and a cluster marker appears.
* @property {boolean} [ignoreHidden=false] Whether to ignore hidden markers in clusters. You
* may want to set this to true to ensure that hidden markers are not included
* in the marker count that appears on a cluster marker (this count is the value of the
* text property of the result returned by the default calculator).
* If set to true and you change the visibility of a marker being clustered, be
* sure to also call MarkerClusterer.repaint().
* @property {boolean} [printable=false] Whether to make the cluster icons printable. Do not
* set to true if the url fields in the styles array
* refer to image sprite files.
* @property {string} [title=""] The tooltip to display when the mouse moves over a cluster
* marker.
* @property {function} [calculator=MarkerClusterer.CALCULATOR] The function used to determine
* the text to be displayed on a cluster marker and the index indicating which style to use
* for the cluster marker. The input parameters for the function are (1) the array of markers
* represented by a cluster marker and (2) the number of cluster icon styles. It returns a
* {@link ClusterIconInfo} object. The default calculator returns a
* text property which is the number of markers in the cluster and an
* index property which is one higher than the lowest integer such that
* 10^i exceeds the number of markers in the cluster, or the size of the styles
* array, whichever is less. The styles array element used has an index of
* index minus 1. For example, the default calculator returns a
* text value of "125" and an index of 3
* for a cluster icon representing 125 markers so the element used in the styles
* array is 2.
* @property {Array} [styles] An array of {@link ClusterIconStyle} elements defining the styles
* of the cluster markers to be used. The element to be used to style a given cluster marker
* is determined by the function defined by the calculator property.
* The default is an array of {@link ClusterIconStyle} elements whose properties are derived
* from the values for imagePath, imageExtension, and
* imageSizes.
* @property {number} [batchSize=MarkerClusterer.BATCH_SIZE] Set this property to the
* number of markers to be processed in a single batch when using a browser other than
* Internet Explorer (for Internet Explorer, use the batchSizeIE property instead).
* @property {number} [batchSizeIE=MarkerClusterer.BATCH_SIZE_IE] When Internet Explorer is
* being used, markers are processed in several batches with a small delay inserted between
* each batch in an attempt to avoid Javascript timeout errors. Set this property to the
* number of markers to be processed in a single batch; select as high a number as you can
* without causing a timeout error in the browser. This number might need to be as low as 100
* if 15,000 markers are being managed, for example.
* @property {string} [imagePath=MarkerClusterer.IMAGE_PATH]
* The full URL of the root name of the group of image files to use for cluster icons.
* The complete file name is of the form imagePathn.imageExtension
* where n is the image file number (1, 2, etc.).
* @property {string} [imageExtension=MarkerClusterer.IMAGE_EXTENSION]
* The extension name for the cluster icon image files (e.g., "png" or
* "jpg").
* @property {Array} [imageSizes=MarkerClusterer.IMAGE_SIZES]
* An array of numbers containing the widths of the group of
* imagePathn.imageExtension image files.
* (The images are assumed to be square.)
