WIP: Implement basic RC pressure boundary condition

Kurt Sansom requested to merge kayarre/nektar:feature/RC_BC into master

This WIP is to add the feature of implementing reduced order pressure boundary conditions into the IncNavierStokes Solver.

This is a merged attempt I made last year at implementing an RC pressure boundary condition. I have created a new revision from current master. The Merge is currently untested, but may be a starting point for Zhen Xiong who emailed about it.

Two issues need to be resolved. 1. I was having issue correctly calculating the flow rate and wasn't the same from timestep to timestep. 2. The behavior when last worked on it was such that the pressure didn't equilabrate properly even when a static pressure was applied.
