 - SCIPnetmatdecCreate() and SCIPnetmatdecFree() for creating and deleting a network matrix decomposition. SCIPnetmatdecTryAddCol() and SCIPnetmatdecTryAddRow() are used to add columns and rows of the matrix to the decomposition. SCIPnetmatdecContainsRow() and SCIPnetmatdecContainsColumn() check if the decomposition contains the given row or columns. SCIPnetmatdecRemoveComponent() can remove connected components from the decomposition. SCIPnetmatdecCreateDiGraph() can be used to expose the underlying digraph. SCIPnetmatdecIsMinimal() and SCIPnetmatdecVerifyCycle() check if certain invariants of the decomposition are satisfied and are used in tests.
 - SCIPfreeReaderdataCor(), SCIPfreeReaderdataTim() and SCIPfreeReaderdataSto() for freeing the data for the COR, TIM and
   STO readers respectively. These readers are all used when reading an SMPS instance.
