	Module merger
	Overview
	The ``merger`` module takes a stream of tuples and provides access to them as tables.
	Index
	The four functions for creating a merger object instance are:
	:ref:`merger.new_tuple_source() <merger-new_tuple_source>`,
	:ref:`merger.new_buffer_source() <merger-new_buffer_source>`,
	:ref:`merger.new_table_source <merger-new_table_source>`,
	:ref:`merger.new(merger_source...) <merger-new_merger_source>`.
	The methods for using a merger object are:
	:ref:`merger_object:select() <merger-select>`,
	:ref:`merger_object:pairs() <merger-pairs>`.
	Create a new merger instance from a tuple source.
	A tuple source just returns one tuple.
	The generator function ``gen()`` allows creation of multiple tuples via an iterator.
	The ``gen()`` function should return:
	state, tuple each time it is called and a new tuple is available,
	nil when no more tuples are available.
	Parameters
	function for iteratively returning tuples
	parameter for the gen function
	return
	merger-object :ref:`a merger object <merger-object>`
	Example: see :ref:`merger_object:pairs() <merger-pairs>` method.
