Resolves #566

Release Notes

• Added optional scaffold surface support to URIS valve via Scaffold_file_path
• Computed scaffold surface unsigned distance function (UDF) on fluid nodes using existing URIS SDF routines
• Scaffold surfaces remain fixed during the simulation and add a resistive force to the fluid

Testing

• Updated the URIS CFD test case to include a scaffold surface

@hanzhao2020 These changes look good !

However, there are still lots of messages printed to std::cout in uris.cpp; please replace those with DebugMsg calls.

@ktbolt Sounds good! Replaced all the URIS printed messages with DebugMsg.
