Detailed Description

Used to describe how a domain shall be distributed in a parallel environment.

A partition map holds a subset handler and a map, which specifies the target process of each subset. Make sure to assign a grid before performing the partitioning.

Todo:

a partition map should feature a constructor which takes a grid.
