### Operations
> capitalized ones are only for pos-oriented, not value
```cpp
// insert an element at a given position in the list
insert(element, POSITION);
// append an element at the end of the list
APPEND(element);
// remove the element at a given position in the list
remove(position);
// remove all the elements from the list
removeAll();
// get the element at a given position in the list
elementType get(position);
// swap two elements
SWAP(position1, position2);
// how many elements are in the list
int getElementCount();
