Expression of type ExprTuple

from the theory of proveit.core_expr_types.tuples

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

# import Expression classes needed to build the expression

# build up the expression from sub-expressions

assert expr == stored_expr
assert expr._style_id == stored_expr._style_id
