==== Iterator handling ====
* Our implementation of begin(/end) returning (const_)iterator is bugged, i.e. the current implementation for iterators of Common::List will not work with code like:
    Common::List<int> list;
    Common::List<int>::const_iterator x = list.begin();
It will fail with (i.e. gcc 4.2.3):
    error: conversion from ‘Common::List<int>::Iterator<int>’ to non-scalar type ‘Common::List<int>::Iterator<const int>’ requested
This is since our Common::List::Iterator implementation does not supply a copy constructor from Common::List::Iterator<int> to the specific type. Check for example Common::HashMap::Iterator for a (rather hacky) implementation of it, or [http://gcc.gnu.org/onlinedocs/libstdc++/latest-doxygen/stl__tree_8h-source.html#l00221 the GNU libstdc++ implementation] (example for std::map iterators).
* Implement proper reverse_iterators for Common::List. Our current implementation is the same as forward iterators, just that rbegin will return the last element instead of the first and there is no rend. Check [http://www.sgi.com/tech/stl/ReverseIterator.html SGI Documentation] for proper description of revese_iterator in the STL.
