 * SUMMARY: Testing |splice()| method of an Array. 
 *          Changes the content of an array, adding new elements while removing old elements.
 *
 *          Syntax: splice(index, howMany, [element1][, ..., elementN]) 
 *
 *          Parameters: index - index at which to start changing the array.  
 *          howMany - An integer indicating the number of old array elements to remove.
 *          If howMany is 0, no elements are removed. In this case, you should specify at least one new element.  
 *          element1, ...,elementN - The elements to add to the array. If you don't specify any elements, 
 *          splice simply removes elements from the array.
