PR Title: Tpetra: Fix #5038 (spurious "unused function" build warnings)
PR Author: mhoemmen

As part of this work the headers SetupRegionMatrix and SetupRegionHierarchy are partially rewritten to fix the Xpetra path.
Additionally a coarse grid solve using Tpetra/Amesos2 is added and gets resonable convergence improvements.
Since we have things working, we should protect them with tests.
This provides a small first test in 2D that performs correctly with coarse grid solve.

1) issue warning for missing coarse solver
Coarse level solver has not been migrated to Xpetra yet.
For now, we just skip it and don't do anything on the coarse level.
However, proc 0 writes a warning message to the screen.

2) Fix map when reading input matrix
Use the composite map instead of creating a linear map when reading
the input matrix.
Remove obsolete function argument

3) Specify example via command line:
The HHG driver reads various input files. The exact example has to be
known in order to setup the structured region MG. Now, the exaxt
name of the example has to be passed via a command line arguement
"--caseName=..."

Add include guards
Move utilities to utils file

Part of #4084.

This is a starting point only, actually some difficulties with the LIDRegion, appData and myRegions arrise quickly preventing further progress.
Also removing unsued variables from research region_algorithms/Driver.cpp

After creating the hierarchy, we need to now its number of levels in
order to run the HHG-specific V-cycle. For now, we extract this
information from the HHG prolongator data structure.

Part of #4084.

Note: also fix Matlab syntax. Use ' instead of " and move LID widget to Utils file

The idea is to seperate some capabilites from the actual driver in order to develop more generic HHG headers.
These headers can then be included in various driver instead of the current in-place use.
This new header defines hierarchy setup functions and the vCycle.
It could be renamed RegionMG but let's think about that later.
It exposes a better split among various functions that are used in the Region MG algorithm.
A few const qualifiers have been modified to be more accurate.

This work aims at fixing the issue reported in #4989.
The error looks like a typo a copy-paste mistake.
