Hi, lets say i have two arbitary container of any stl type.

template
<
class T,
template <typename ELEM, typename = std::allocator<ELEM> >
class CONT
>
typename boost::enable_if<boost::is_floating_point<T>, T>::type
getManhattanDistance(const CONT<T>& ObjectX, const CONT<T>& ObjectY)

I want to be able to iterate through both containers to get the euclidean
distance.. i.e.

sqrt of sum of each item in ObjectX  - ObjectY square.

Psuedocode looks like this..
/***********************************************
*   getManhattanDistance(ObjectX, ObjectY)     *
*   overAllSum <-- 0                           *
*   for i <-- 0 to sizeof (ObjectX)            *
*       Xn <-- ObjectX[i]                      *
*       Yn <-- ObjectY[i]                      *
*       difference <-- (Xn - Yn) * -1          *
*       overAllSum <-- overAllSum + difference *
***********************************************/

but i want to make it as abstract (allowing nonindexable containers) but
also clear as possible without losing speed. Whats the best way to do this
using boost library.
