/**
* Class: OpenLayers.Control

* from panning and zooming to displaying a scale indicator. Controls by
* default are added to the map they are contained within however it is
* possible to add a control to an external div by passing the div in the
* options parameter.
*
* Example:
* The following example shows how to add many of the common controls
* to a map.
*
* > var map = new OpenLayers.Map('map', { controls: [] });
* >
* > map.addControl(new OpenLayers.Control.PanZoomBar());
* > map.addControl(new OpenLayers.Control.MouseToolbar());
* > map.addControl(new OpenLayers.Control.LayerSwitcher({'ascending':false}));
* > map.addControl(new OpenLayers.Control.Permalink());
* > map.addControl(new OpenLayers.Control.Permalink('permalink'));
* > map.addControl(new OpenLayers.Control.MousePosition());
* > map.addControl(new OpenLayers.Control.OverviewMap());
* > map.addControl(new OpenLayers.Control.KeyboardDefaults());
*
* The next code fragment is a quick example of how to intercept
* shift-mouse click to display the extent of the bounding box
* dragged out by the user. Usually controls are not created
* in exactly this manner. See the source for a more complete
* example:
*
* > var control = new OpenLayers.Control();
* > OpenLayers.Util.extend(control, {
* > draw: function () {
* > // this Handler.Box will intercept the shift-mousedown
* > // before Control.MouseDefault gets to see it
* > this.box = new OpenLayers.Handler.Box( control,
* > {"done": this.notice},
* > {keyMask: OpenLayers.Handler.MOD_SHIFT});
* > this.box.activate();
* > },
* >
* > notice: function (bounds) {
* > OpenLayers.Console.userError(bounds);
* > }
* > });

* is represented by x2 and y2. Start and end are ordered so that x1 < x2.

* and y2. The start point is represented by x1 and y1. The end point
* is represented by x2 and y2. Start and end are ordered so that x1 < x2.
* options - {Object} Optional properties for calculating the intersection.
*
* Valid options:
* point - {Boolean} Return the intersection point. If false, the actual
* intersection point will not be calculated. If true and the segments
* intersect, the intersection point will be returned. If true and
* the segments do not intersect, false will be returned. If true and
* the segments are coincident, true will be returned.
* tolerance - {Number} If a non-null value is provided, if the segments are
* within the tolerance distance, this will be considered an intersection.
* In addition, if the point option is true and the calculated intersection
* is within the tolerance distance of an end point, the endpoint will be
* returned instead of the calculated intersection. Further, if the
* intersection is within the tolerance of endpoints on both segments, or
* if two segment endpoints are within the tolerance distance of eachother
* (but no intersection is otherwise calculated), an endpoint on the
* first segment provided will be returned.
*
* Returns:
* {Boolean | <OpenLayers.Geometry.Point>} The two segments intersect.
* If the point argument is true, the return will be the intersection
* point or false if none exists. If point is true and the segments
* are coincident, return will be true (and the instersection is equal

* listener for the corresponding event. When a handler is deactivated,
* those same methods are unregistered as event listeners.
*
* Handlers also typically have a callbacks object with keys named like
* the abstracted events or event sequences that they are in charge of
* handling. The controls that wrap handlers define the methods that
* correspond to these abstract events - so instead of listening for
* individual browser events, they only listen for the abstract events
* defined by the handler.
*

* Create a new XMLHttpRequest object, open it, set any headers, bind

* This method is only documented to provide detail on the configuration

*
* Parameters:
* config - {Object} Object containing properties for configuring the
* request. Allowed configuration properties are described below.
* This object is modified and should not be reused.
*
* Allowed config properties:
* method - {String} One of GET, POST, PUT, DELETE, HEAD, or
* OPTIONS. Default is GET.
* url - {String} URL for the request.
* async - {Boolean} Open an asynchronous request. Default is true.
* user - {String} User for relevant authentication scheme. Set
* to null to clear current user.
* password - {String} Password for relevant authentication scheme.
* Set to null to clear current password.
* proxy - {String} Optional proxy. Defaults to
* <OpenLayers.ProxyHost>.
* params - {Object} Any key:value pairs to be appended to the
* url as a query string. Assumes url doesn't already include a query
* string or hash. Typically, this is only appropriate for <GET>
* requests where the query string will be appended to the url.
* Parameter values that are arrays will be
* concatenated with a comma (note that this goes against form-encoding)
* as is done with <OpenLayers.Util.getParameterString>.
* headers - {Object} Object with header:value pairs to be set on
* the request.
* data - {String | Document} Optional data to send with the request.
* Typically, this is only used with <POST> and <PUT> requests.
* Make sure to provide the appropriate "Content-Type" header for your
* data. For <POST> and <PUT> requests, the content type defaults to
* "application-xml". If your data is a different content type, or
* if you are using a different HTTP method, set the "Content-Type"
* header to match your data type.
* callback - {Function} Function to call when request is done.
* To determine if the request failed, check request.status (200
* indicates success).
* success - {Function} Optional function to call if request status is in
* the 200s. This will be called in addition to callback above and
* would typically only be used as an alternative.
* failure - {Function} Optional function to call if request status is not
* in the 200s. This will be called in addition to callback above and
* would typically only be used as an alternative.
* scope - {Object} If callback is a public method on some object,
* set the scope to that object.
*
* Returns:
* {XMLHttpRequest} Request object. To abort the request before a response
* is received, call abort() on the request object.
