a MEDCouplingField with extra information related to parallel
topology.

It is most conveniently created by giving a pointer to a MEDCouplingField
object and a \c ProcessorGroup.
By default, a ParaFIELD object will be constructed with all field components
located on the same processors. In some specific cases, it might be necessary to scatter components over several processors. In this case, the constructor
using a ComponentTopology is required.
