remember fmtflags and reset them at the end of print functions.

Thanks to bernd Flemisch for the hint.

graph.
This is proposed for elasticity problems by several people.
(Works better for Olivers problems).

Still we need a direct solver here *sigh*

If this is the case find will return the end iterator.

Fixes flyspray #222

Prevent using too much memory.

Only the nonzeros blocks are printed here (without any dots for zero entries).

In operator= for assigning a BCRSMatrix that was constructed without
specifying the number of nonzero one has to calculate the number of
nonzeros before allocating memory.

const qualifier makes no sense.

Do not overwrite index. Is this is a bug if lower_bound returns the
end iterator.

added check whether row has nonzero size.

Fixes flyspray 202.

Rely on MPI daemons being started.

The problem was with row pointers of empty rows being initialized to the same value
as the previous nonempty row (or to the first data element if no such rows existed).

Fixed this.

Reduced duplicate code.

Force lower bound to use std::less<IndexPair> instead of
std::less<int> as LessThanComparator.
