Title: Refactor dof table construction

Mainly moving createDofTable() function into LocalToGlobalIndexMap constructor.
This removes duplicate code from the GroundwaterFlowProcess and the SteadyDiffusion2D test.

Other important changes are of technical nature:
- Iterator access for mesh's elements
- Disable implementation of LocalToGlobalIndexMap for parallel environments. This was not implemented or tested anyway.
