[CIG-LONG] Boundary Velocity Conditions

Velocity BCs are quite flexible in SNAC.
Often called free-slip BCs, reflective BCs are easy to apply.
You only need to set the normal component of velocity to a boundary to
be zero, leaving the other two components unspecified.
However, periodic BCs are not possible. Probably not needed in a
Lagrangian code like SNAC, either.
Please let me know if you are thinking about a particular problem where
such BCs are required.
Any ways, two cookbook examples will give you some idea on how to apply
velocity BCs.
Let me know if you have further questions.
Cheers,
Eunseo
