element : The element after which the new element is to be inserted.

Appends an element to the specified element of list, initializing the element's data field with a specified value.

The element's value will be set using the copy constructor for type T.

void append (const T &data, Element *element)

`data` :	The value to be assigned to the data field of the newly created element.
`element` :	The element after which the new element is to be inserted.

Prepends an element to the specified element of the list, initializing the element's data field with a specified value.

The element's value will be set using the copy constructor for type T.
