Detailed Description

template<typename T, typename TAlloc = std::allocator<T>, bool usePointers = false>
class DGtal::IVector< T, TAlloc, usePointers >

Next, we want to define the storage class IVector<T, Alloc, usePointers>. It behaves like a subset of std::vector<T>'s capabilities (i.e. access elements, get size, set size, get last element, swap with other storage of same type), but uses std::vector<T*> in case usePointers is true.

The advantage of this approach is that if T is a more complex object, reallocation done with resize() can be very costly.

This generic version is just using std::vector<T>.
