Detailed Description

class to encapsulate the operations of ghost-cell boundary conditions.

BoxGhostBC is a class to encapsulate the operations of ghost-cell boundary conditions at a face. If the solution is phi and the face normal direction is x, the boundary conditions usually used can be expressed as A*phi + B*dphi/dx = C. The derived class provides a function to to fill A B and C. These functions are only meant to be called by DomainGhostBC.
