Class for a complex-valued, parallel linear form
The convention argument in the class's constructor is documented in the mfem::ComplexOperator class found in linalg/complex_operator.hpp.
When supplying integrators to the ParComplexLinearForm either the real or imaginary integrator can be NULL. This indicates that the corresponding portion of the complex-valued field is equal to zero.
