function Maximum2d( mergedElements ) {

	// Maximum2d inherits from abstract strategy "StableMerge2d".
	
	StableMerge2d.call( this, mergedElements );

	this.strategyType = "Maximum2d";

}
Maximum2d, can be initialized by StrategyFactory directly.
MergeStrategy for MergedLayer when apply Maximum operation to 2d TensorSpace layers.

For example:
```javascript
let conv1d1 = new TSP.layers.Conv1d( { ...config } );
let conv1d2 = new TSP.layers.Conv1d( { ...config } );
let maximumLayer = TSP.layers.Maximum( [ conv1d1, conv1d2 ], { ...config } );
```
In this example, the merged layer "maximumLayer" apply merge strategy "Maximum2d".

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