- Don't use this for simple types such as "int" or "long"! - You _may_ use it for "double" but it's awfully inefficient. -

- Note on Add/Insert functions: -
- 1) function(T*) gives the object to the array, i.e. it will delete the - object when it's removed or in the array's dtor -
- 2) function(T&) will create a copy of the object and work with it -
-
- Also: -
- 1) Remove() will delete the object after removing it from the array -
- 2) Detach() just removes the object from the array (returning pointer to it) -
-
- NB1: Base type T should have an accessible copy ctor if Add(T&) is used, -
- NB2: Never ever cast a array to it's base type: as dtor is not virtual - it will provoke memory leaks -
