Detailed Description
Implementation of MinorantExtender for SOCSupportFunction.
This object will be returned as an object on the heap by SOCSupportFunction::apply_modification and will be deleted by ConicBundle after use. Its purpose is to fill up further coordinates of the minorant (if this is possible).

- Parameters
-
[in,out] minorant (Minorant&) it holds a (possibly aggregated) minorant that was generated from minorants returned by oracle calls, e.g. as in FunctionOracle::evaluate() If PrimalData was provided in these minorants, this will be aggregated along and will also be available in this minorant. [in] n_coords (int) the number of coordinate positions that have to be filled in [out] indices (const int*) the indices of these coordinate positions (sorted in strictly increasing order)
- Returns
- 0 on success,
- 1 if extension is impossible
