document pv
Prints std::int_vector<width> information.
Syntax: pv <int_vector> <idx1> <idx2>
Note: idx, idx1 and idx2 must be in the range [0..<int_vector>.size()-1].
Examples:
pv v - Prints vector content, size, capacity and T typedef
pv v 0 - Prints element[idx] from int_vector
pv v 1 2 - Prints elements in range [idx1..idx2] from int_vector
end
