The presolve action for this class removes explicit zeros from the constraint matrix. The postsolve action puts them back.

| const char* drop_zero_coefficients_action::name | ( | ) | const [inline, virtual] |
A name for debug printing.
It is expected that the name is not stored in the transform itself.
