Check if one of two sets is a subset of the other set.

one_thisis the index in this sparse_sizevec object of the first set.
two_otheris the index in other sparse_sizevec object of the second set.
otheris the other sparse_sizevec object which may be the same as this object.
If zero, niether set is a subset of the other. If one, then one is a subset of two and they are not equal. If two, then two is a subset of one and they are not equal. If three, then the sets are equal.
