Only apply the parameter output_symmetry_points at outer boundaries.
Only apply the parameter out3D_outer_ghosts if this is not a symmetry
boundary.
Unify handling of output_symmetry_points, out3D_ghosts, and
out3D_outer_ghosts.

This currently works only in full or octant mode. For
bitant (and other modes) a generalization is needed and planned.

An consistency check has been added at simulation startup
to parse the values of the IOASCII::out[0-3]d_vars parameters and print
a level 0 or 1 warning message (depending on IO::strict_io_parameter_check)
if they contain an invalid variable/group name.

Add a parameter CarpetIOASCII::one_file_per_group that collects the
output for all variables of a group into a single file. This reduces
the number of files, and should thus speed up output and reduce disk
usage.
If at least one variable of a group is output, then the whole group is
output.

Do not use CCTK_QueryParameterTimesSet to find out whether to use a
parameter value from this thorn, or from IO. Use special parameter
values for that instead, and make these the default.

Add 0-dimensional ("point") output. This is necessary to output grid
scalars.
Make the output triggering on all refinement levels be independent.
Honour do_global_mode when outputting grid scalars and grid arrays.

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.

Major update after a quiet time.
Carpet: The flesh now has new cGH fields cctk_levoff[],
cctk_levoffdenom[], and cctk_timefac that describe the spatial offset
and temporal refinement factor between the base and the current
refinement level. These fields are now set and used; they change how
coordinates are handled.
CarpetIOASCII: Fix bugs regarding choosing the output hyperslab and
the output coordinates.
ID*, *Toy*: New WaveToy examples with various formulations and
different integrations methods. Currently, none of them converge to
second order except the standard WaveToy formulation.
These updates require the recent flesh, base thorn (and MoL) updates.

Fixed a bug in CarpetSlab; was using the local instead of the global
extent.
Added a more comfortable way to specify the refined region. The new
method has no restrictions.
Added a way to specify the location of the outer boundary explicitely.
Added dummy parameter "periodic*" so that Carpet can be used as
drop-in replacement of PUGH (at least when running without
refinement).

CarpetIOASCII.
Added parameter to not output the ghost zones for ASCII output.

Extented Carpet to handle multiple grid components per processor.
Currently works on one processor only.
