function Maximum3d( mergedElements ) {

	// Maximum3d inherits from abstract strategy "StableMerge3d".
	
	StableMerge3d.call( this, mergedElements );

	this.strategyType = "Maximum3d";

}
Maximum3d, can be initialized by StrategyFactory directly.
MergeStrategy for MergedLayer when apply Maximum operation to 3d TensorSpace layers.

For example:
```javascript
let conv2d1 = new TSP.layers.Conv2d( { ...config } );
let conv2d2 = new TSP.layers.Conv2d( { ...config } );
let maximumLayer = TSP.layers.Maximum( [ conv2d1, conv2d2 ], { ...config } );
```
In this example, the merged layer "maximumLayer" apply merge strategy "Maximum3d".

@param mergedElements, array of TensorSpace layers. (layerList.length > 0)
@constructor
