Judging from ParallelDebugOutput.hh this is what is should be.
Before this commit it was empty as it had space reserved but never
any entries pushed (they were inserted with operator[]).
This reverts commit dde79daf4ec2004148a58250c4c8af5390251689.
Judging from ParallelDebugOutput.hh this should not be a map from element
index to interior element index, but an a list of indices of all interior
elements. Therefore we need to reserve and later on push_back.
This reverts commit 09db2fd412abe4b8a2f52274bcc0041e4b20a94d.

Previously distributedCartesianIndex was resized and afterwards all
entries were added with push_back. Therefore the array was twice as
big as expected and contained wrong values in the front.
With this commit we insert the values using random access. Thus the
size is as expeceted and the index of the entries do not depend on the
order of the grid traversal.
While it may not produce memory errors it is semantically wrong to insert
entries with random acces into a vector that has reserved enough memory to
hold the values but still has size 0.
