Class
    Foam::SubDimensionedField
 
Description
    SubDimensionedField is a DimensionedField obtained as a section of another
    DimensionedField.
 
    Thus it is itself unallocated so that no storage is allocated or
    deallocated during its use.  To achieve this behaviour,
    SubDimensionedField is derived from SubField rather than Field.
