Use CARPET_DEBUG and CARPET_OPTIMISE (instead of NDEBUG) to decide
whether to perform or omit somewhat expensive self checks. When
CARPET_DEBUG is defined, even expensive checks are performed. When
CARPET_OPTIMISE is defined, even cheap checks are omitted.

Add namespace CarpetLib::good containing overloaded abs functions for
all Cactus datatypes. Some C++ compilers do not have long long
support for abs, i.e., either std::abs or llabs does not exist. This
circumvents this problem.

CarpetLib contained special code that used std::complex instead of
Cactus's CCTK_COMPLEX for complex variables. A very similar feature
is now supposed to go into the flesh, and hence this (unused) code is
being removed.

Define a macro AT() to index into std::vector. Depending on the macro
NDEBUG, AT() is defined either as at(), providing index checking, or
as operator[], providing no checking.

Reorganise prolongation and restriction operators. This is a major
implementation change.
Most operators are now written as C++ templates instead of as Fortran
77 code. This simplifies the code, since C++ routines can be called
more easily, and they also have access to CarpetLib's high-level data
structures.
Previously, the operators combined temporal and spatial interpolation.
Now, time interpolation and space interpolation are handled
separately. This may be less efficient, but simplifies the code
significantly, since there are now N+M instead of N*M routines, for N
time interpolation and M space interpolation methods.
Remove the minmod prolongation operator, which was previously
disabled.
Add support for cell centering, using a method described by Simon
Hern, and suggested for Carpet by Ian Hawke.

The new datatype region_t combines an extent (a bbox), an outer
boundary descriptor, a refinement descriptor, and a processor number:
struct region_t {
ibbox extent; // extent
b2vect outer_boundaries; // outer boundaries
b2vect refinement_boundaries; // refinement boundaries
int map; // map to which this
// region belongs
int processor; // processor number
};
These quantities are often used together, and combining them into a
single datatype simplifies the code significantly.
Adapt gh, dh, etc. to use this new datatype.
This is a major API change.

These types are
typedef vect<vect<bool,dim>,2> b2vect;
typedef vect<vect<int,dim>,2> i2vect;
They are similar to bbvect and iivect, but have the order reversed.
They are useful if you need one element per face of a grid variable.

Turn most of the templates in CarpetLib, which used to have the form
template<int D> class XXX
into classes, i.e., into something like
class XXX
by setting D to the new global integer constant dim, which in turn is set to 3.
The templates gf and data, which used to be of the form
template<typename T, int D> class XXX
are now of the form
template<typename T> class XXX
The templates vect, bbox, and bboxset remain templates.
This change simplifies the code somewhat.

Import the recently announced changes:
1. Carpet has now an infrastructure for multiple maps (aka "grid
patches"). Instead of a single grid hierarchy there can now be
several. This is largely untested, because the remainder of Cactus
cannot handle multiple coordinate systems.
2. The order in which the schedule bins are called has changed. As Ian
Hawke pointed out, the previous order during time evolution was
inconsistent. The initial data ordering did not allow for recovering
and was not usable for progressively solving elliptic equations for
initial data.
3. Carpet now supports convergence levels. The convergence level
specifies by how many factors of two the resolution in the parameter
file should be coarsened (or refined, if negative). This should make
convergence tests and test runs much easier. It is, in principle, also
possible to run several convergence levels at once. This has not been
tested because the remainder of Cactus cannot handle multiple
resolutions. This will be necessary for a multigrid solver, and also
for having a shadow hierarchy to determine where to refine adaptively.
4. Carpet works together with the new CoordBase domain specification
parameters. Without these, using convergence levels will lead to very
strange results.
5. The "modes" have changed. There are now:
meta mode: the whole simulation
global mode: one convergence level
level mode: one refinement level
singlemap mode: one map on one refinement level
local mode: as previously
The whole mode handling has been cleaned up.
6. The regridding thorn has been cleaned up.
7. The kind of prolongation stencil is now determined in Carpet, i.e. at
a fairly hight level, instead of in CarpetLib.
8. The low-order prolongation operators have been made much more
efficient (as have previously the higher-order ones).
9. Assorted smaller changes.
For Carpet users, there should be no major incompatibilities. The major
improvements are 3 and 4 combined. Here is an example:
CoordBase::domainsize = extent
CoordBase::spacing = gridspacing
CoordBase::zero_origin_x = yes
CoordBase::zero_origin_y = yes
CoordBase::zero_origin_z = yes
CoordBase::xextent = 20.0
CoordBase::yextent = 20.0
CoordBase::zextent = 20.0
CoordBase::dx = 1.0
CoordBase::dy = 1.0
CoordBase::dz = 1.0
CoordBase::boundary_shiftout_x_lower = 1
CoordBase::boundary_shiftout_y_lower = 1
CoordBase::boundary_shiftout_z_lower = 1
Carpet::domain_from_coordbase = yes
Carpet::convergence_level = 0
grid::type = coordbase
grid::domain = octant
grid::avoid_origin = no
This gives you a grid that extends from the origin ("zero_origin") up to
20.0 with a grid spacing of 1.0. Symmetry zones and boundary zones are
added automatically. The "shiftout" says that there is no boundary
point on the origin. The staggering parameters (not shown) default to
"no". In order to change the resolution, only the convergence level
has to be adjusted. Note that the old way of specifying the domain
extent still works.
For Carpet developers, one major change is the new mode handling. As
described in 5, the looping macros (that loop over all refinement
levels, or all components) have changed.

Add normalize routine to normalise bboxsets. This isn't perfect yet,
i.e. it still misses some cases.
Fix bug in calculating the regions that should be restricted to:
exclude all regions used as source for boundary prolongations, even if
these prolongations go to a different processor.

Removed the "dimgeneric_*" data types from CarpetLib. They were never
really used anyway.

Removed user choice of C++ template instantiation model. In my
experience, only one model works, namely explicit template
instantiaion. No need to pretend that the other things work with
Cactus.
(Don't complain to me -- I also think it's a shame that something that
calls itself "compiler" isn't able to do this automatically. Many
other compilers for many other languages do this kind of thing without
even mentioning it. So there's either something fundamentally wrong
with the C++ standard, or with the C++ compiler writers, or with the
perceived wishlists of C++ users. And I would bet an arm and a leg
that it's not the second of these.)

Added stream input routines for some CarpetLib containers.
The regridder now has to explicitly say which boundaries are outer,
and which are internal. This will make outer boundaries on fine grid
possible, and is also necessary when there are multiple grid patches.
Started to add support for arbitrariliy many user-specified refinement
regions. Not yet finished.
The Carpet driver can now handle multiple grid patches.
Added example files for multiple grid patches. They use initial data
that does not "fit" the boundary conditions, and they don't use
multiple refinement levels so far.
Removed old and unused example files in CarpetLib.

Cleaned up the code to make it work with multiple multigrid levels

Added simple recombining to the clusterer. This should lead to fewer
grid components. Not very tested.
