 * @brief  Simple and fast LP rounding heuristic
 * @author Tobias Achterberg
 *
 * Simple rounding is a very cheap heuristic that iterates over the set of fractional variables of an LP-feasible
 * point. It only performs roundings for variable that have zero up- or downlocks. Hence, they are guaranteed to keep
 * all constraints satisfied.  If all fractional variables can be rounded that way, the resulting solution will bve
 * integral and LP-feasible.
