/*!\file ProcessParamsx
 * \brief: process parameters using partitioning vector. 
 * Go through all parameters in the 'parameters' dataset. For each parameter that holds a doublevec (ie, a double* vector synchronized across 
 * the MPI ring of a cluster), partition the vector so that the new node partitioning decided in ModelProcessor is applied. Otherwise, 
 * parameters coming directly from Matlab would be serially partitioned, which means could not be recognized by each individual node or element. 
 * The partition needs to be the parallel partitionting.
