Improved FunctionBase constructDocument parameter propagation

* replaced std::tuple constructing Mapper template methods with direct XObjectArgVectorType unpacking
** XObjectValue::get template method is applied directly using parameter pack unpacking
* implemented custom IndexSequence / Sequence type to provide vector indexes
* modified all external functions to provide matching constructDocument overloads
