Added external access to a few Vars within the StokesVGPFormulation.
Added support for "enhanced" fluxes--to match the test space degree--to VGP Navier-Stokes.  But experiments thus far have failed rather miserably.
Fixed error in which vector HVOL bases had extra p-order.
Added more output to cavity flow and hemker driver, for Navier-Stokes paper.
Added column for "combined relative error" to HConvergenceStudy output.
Added some commented-out code to allow matching Leszek's triangular meshes.
Added StokesStudyForLeszek.
