1 !> @brief Module containing implementations of various local m-form constraints, such as:
2 !> - MFormDirichlet, which imposes a Dirichlet boundary condition on an m-form
3 !> - MFormNeumann, which imposes a Neumann boundary condition on a 0-form
4 !> - MFormUniqueness constraint, which imposes a uniqueness constraint on an m-form (e.g., to fix the constant mode in a purely periodic Poisson problem)
