Detailed Description

template<typename TYPE, typename TOCHECKFUNCTOR = CheckAllFunctor<TYPE>>
class tlp::UniqueIterator< TYPE, TOCHECKFUNCTOR >

UniqueIterator enables to remove duplicated elements in an iterator.

Parameters:

it	the iterator in which we want to filter out duplicated elements
checkFuncor	a functor that enable to indicate wheter or not the element could be duplicated (default test all elements)

The functor function shoul have the following form

 class ACheckFunctor {
  bool operator(TYPE a) {
   return true if a could be duplicated else false;
  }
 };

checkFunctor are used for optimization purpose to prevent to log(n) test for all elements when not necessary.
