This library defines a set of functions to delete the content of an STL container
containing pointers to objects.
Two functions exist:
delete_container just applies the
delete operator to each element of container.
vector_delete_container applies the
delete  operator to each element.
After deleting the elements, the container is cleared, leaving it empty.
Additionally, two classes exist:
These classes just wrap the STL container
Container, and invoke
vector_delete_container() respectivelly in the destructor.
