[MFC] vector-shift-left

[Philip Nicoletti]

There is a function std::rotate() in <algorithm> (but you have to
set the last element yourself). Here is an example using
rotate with std::vector ... it also works with an array or CArray,
\but the call will be slightly different:

std::vector<int> v;

for (int i=0; i<6; ++i)
{
   v.push_back(i+1);
}

std::rotate(v.begin(),v.begin()+1,v.end());
v[5] = 7;
