  -Partial Assembly for Discontinous Galerkin methods support
  -----------------------------------------------------------
  -- Added initial support for matrix free Discontinuous Galerkin methods using
  - a partial assembly operator decomposition. The implementation builds up on
  - the GPU/device support and extends it to easily support face integrators.
  - This initial support requires Gauss-Lobatto basis.
  -
  -- ex9 and ex9p are now supporting partial assembly on CPU and GPU devices.
  - Using partial assembly provides significantly improved performance,
  - particularly on high-order 3D problems using GPU devices.
  -
  -- Include the implementation of a first face integrator: DGTraceIntegrator.
  - Generic and optimnized implementations are provided.
  -
  -- Improved performance for Convection integrator using partial assembly.
