SlidingMarker doesn't define MAX_ZINDEX

[GehDoc]

SlidingMarker doesn't define this property.

Replacing Google Marker globally by using SlidingMarker.initializeGlobally, breaks some code. For exemple, the last version of OverlappingMarkerSpiderfier library.

Ok, let's think how to resolve this issue.
MAX_ZINDEX is not a property on a marker, but instead a constant on google.maps.Marker, so you can access its value like this:

google.maps.Marker.MAX_ZINDEX

Now, please provide your code that causes the problem.

That's exactly my problem.
After a call to SlidingMarker.initializeGlobally(), I can no more use this value :

		// Replace standard markers
		console.log(google.maps.Marker.MAX_ZINDEX); // 1000000
		SlidingMarker.initializeGlobally();
		console.log(google.maps.Marker.MAX_ZINDEX); // undefined -> problem

		map = new google.maps.Map(document.getElementById('map_canvas'), {
			zoom: 12,
			mapTypeId: google.maps.MapTypeId.HYBRID
		});

		// last version 2017/05/02 : https://github.com/jawj/OverlappingMarkerSpiderfier. Not the version you provide (I haven't tested it).
		// broken because it needs google.maps.Marker.MAX_ZINDEX to promote spiderfied markers : they stay at their initial z-index.
		var oms = new OverlappingMarkerSpiderfier(
			map,
			{ 
				markersWontMove: true,
				markersWontHide: true,
				basicFormatEvents: true,
				keepSpiderfied: true,
				circleFootSeparation: 23*1.5,	// default = 23
				spiralLengthStart: 11*1.5,		// default = 11
				nearbyDistance: 20*1.5,			// default = 20
			}
		);

A quick fix which works for me, is to add this code at the end of decorates function of slidingmarker.js file :

        var decorates = function (childCtor, parentCtor) {
            // [...]
            childCtor.MAX_ZINDEX = GoogleMarker.MAX_ZINDEX; // quick and dirty fix
        };

That's certainly not the right way. And other properties may be missing, but I'm not affected.

[GehDoc]

An external solution (without modifying your library) is simpler, directly in my code :

		var MAX_ZINDEX = google.maps.Marker.MAX_ZINDEX;
		SlidingMarker.initializeGlobally();
		google.maps.Marker.MAX_ZINDEX = MAX_ZINDEX;

Oh, sure this is a bug. I will try to fix it ASAP.
Thank you.
