stl::remove does NOT remove elements!
Mental note: stl::remove does NOT remove the elements in a collection. It merely moves the elements to the back of a collection and returns an iterator which points to the first element to be removed.
It can be used as follows:
#include <algorithm> // more stuff here.. myCollection.erase( std::remove( myCollection.begin(), myCollection.end(), myObj), myCollection.end() );
