implied by voting for a given side of a bill. In other words, it determines
which stances a member has that might suggest that the member would vote

bill: the bill whose stances will be used to filter the member stances
side: the side of the bill to examine (e.g. FOR or AGN)
Return:
A list that contains only those member stances that are the same as
those implied by voting on the given side of the bill.
