```Remove small Poly series coefficients.

Parameters
----------
seq : sequence
Sequence of Poly series coefficients. This routine fails for
empty sequences.

Returns
-------(more...)

"""Remove small Poly series coefficients.

Parameters
----------
seq : sequence

empty sequences.

Returns
-------
series : sequence
Subsequence with trailing zeros removed. If the resulting sequence
would be empty, return the first element. The returned sequence may

Notes
-----
Do not lose the type info if the sequence contains unknown objects.
