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

end

document pstring
  Prints std::string information.
  Syntax: pstring <string>
  Example:
  pstring s - Prints content, size/length, capacity and ref-count of string s
