Make sure the global looku is setup!

Thank you very much Bård for providing this patch.
I apologize for the caused inconvenience.

warn about missing Parmetis only if MPI is present.  Why bother sequential programmers with information irrelevant to them?

Fixes flyspray #613

[[Imported from SVN: r1089]]

Really aggregate isolated nodes.
Correctly use all aggregates (isolated and connect) to compute
coarsening rate!

interface. Otherwise the interface is plain wrong!

communication.

Both Interface and BufferedCommunicator loose their template
parameter. It was not needed and hindered the new implementation.
Sorry for the inconvenience.

Please change your code:
Interface<IndexSet> -> Interface
BufferedCommunicator<IndexSet> -> BufferedCommunicator

I hope this is the correct of fixing this. Maybe Markus could take a short look
on this...

repartitioning.
Do not skip isolated nodes. (In parallel they might occur on coarser
level due a not ideal data decomposition)

[[Imported from SVN: r1080]]

Made parallel SOR work with amg.

[[Imported from SVN: r1079]]

[[Imported from SVN: r1078]]

Adapt to interface change.

[[Imported from SVN: r1077]]

Parallel AMG works on helics with repartitioning!

matrixredistribute.hh : Ensure that overlap rows have the right entries
matrixutils.hh : Added method to print a distributed sparse matrix
amg.hh: initialize pointer with zero to prevent deallocation of nonallocated storage.
hierarchy.hh: print operator complexity in verbose mode.
transfer.hh: removed wrong assertions (yes, Index sets can have holes!)
repartition.hh: Bugfix: Use the correct MPI datatype to unpack. (Unpacking a std::size_t using MPI_INT on 64 bit is not a good idea!)

ParMETIS. (The additive version is not yet debugged!!!)
Graph::maxVertex does what it says now
Made index sets accessible in RemoteIndices class.
Fixed some typos.

redistribute the matrix according to it.

Both do not do any error checking.
Introduced at method that does the same but checks for errors.

the underlying index sets and does not want to recompute the remote
index information.
