Expression of type ExprTuple

from the theory of proveit.numbers.multiplication

proveit.defaults.automation = False # This will speed things up.
proveit.defaults.inline_pngs = False # Makes files smaller.

justification	if any wrap positions are set, justify to the 'left', 'center', or 'right'	left	left	('with_justification',)
