Uses isA, not isType

Foam::scalar smallestDist ( const point &  p,
const polyPatch &  patch,
const label  nWallFaces,
const labelList &  wallFaces,
label &  meshFacei 
) const

Calculate smallest true distance (and face index)

from pt to faces wallFaces. For efficiency reasons we still pass in patch instead of extracting it from mesh_
