Copies a range of elements from an Array starting at the specified source index and pastes
them to another Array starting at the specified destination index. The length and the indexes
are specified as 64-bit integers.
sourceArray:
		The Array that contains the data to copy.
sourceIndex:
		A 64-bit integer that represents the index in the sourceArray at which copying begins.
destinationArray:
		The Array that receives the data.
destinationIndex:
		A 64-bit integer that represents the index in the destinationArray at which storing begins.
length:
		A 64-bit integer that represents the number of elements to copy.
