Use less memory for ScMatrix::Collect

The old definition would have unused mnCount s.
The template has been modified to expand functionality.
Redefined operator for sum and sum square.

Memory usage change explanation:

The old code would use an array of IterateResultMultiple.
Then use them to iterate.
The count is stored in a last IterateResultMultiple.

So if we are inputed N operators we are:
Wasting N counters.
Wasting 1 accumulator.

Solution:
We move the array to the accumulator place (inside the structure).
Then we use only N accumulators.
The structure with the array has only 1 counter.
