Detailed Description

Boundary linear integrator for imposing non-zero Dirichlet boundary conditions, to be used in conjunction with DGDiffusionIntegrator. Specifically, given the Dirichlet data u_D, the linear form assembles the following integrals on the boundary:

sigma < u_D, (Q grad(v)).n > + kappa < {h^{-1} Q} u_D, v >,

where Q is a scalar or matrix diffusion coefficient and v is the test function. The parameters sigma and kappa should be the same as the ones used in the DGDiffusionIntegrator.
