Class
    Foam::faePatchField

Description
    faePatchField<Type> abstract base class.  This class gives a fat-interface
    to all derived classes covering all possible ways in which they might be
    used.  The first level of derivation is to basic patchFields which cover
    zero-gradient, fixed-gradient, fixed-value and mixed conditions.  The next
    level of derivation covers all the specialised typed with specific
    evaluation procedures, particularly with respect to specific fields.
