Boundary Conditions and Constructors of Function classes

Hi,

I just noted a small inconsistency in the constructors of the P*VectorFunctions compared to those of the scalar functions. All of

• P1Function
• P2Function
• EdgeDoFFunction
• FaceDoFFunction

provide a constructor version that allows to set a BoundaryCondition. The constructor which does not allow this, in turn delegates to the other one using our default variant BoundaryCondition::create0123BC() to generate a B.C. object.

• P1VectorFunction
• P2VectorFunction

both currently provide only a single constructor that

• does not allow to set the boundary condition
• and also does not set the default

IMHO we should fix this by extending the two classes.

Cheers
Marcus
