/** @class BoundedDivisorsOf
* @brief This class defines defines a function for computing a bounded
* variant of @c MononmialSet's @c divisorsOf
*
This implements the mapping
f: terms -> subsets of T (a set of terms), with
t :> {y in T : t divides y, y divides t*t0}
where t0 and T are a term and a set of terms, respectively,
given as constructor arguments.
* @note The operator stored references of t0 and T only.
