* add dtlapse_evolution and dtshift_evolution method optionsrhaas2012-11-27
| | | | | | | | | | | | This attached patch actually does two things: 1. adds dtlapse_evolution method and dtshift_evolution method options 'exact' to the respective ADMBase keywords 2. schedules metric initialization in MoL_PostStep (in addition to CCTK_PRESTEP) which is in line with what the current gauge initialization routine does git-svn-id: http://svn.einsteintoolkit.org/cactus/EinsteinInitialData/Exact/trunk@284 e296648e-0e4f-0410-bd07-d597d9acff87

Major user-visible changes: * major expansion of doc/documentation.tex * major expansion of documentation in param.ccl file, including a long "how to add a new model" block comment * rename all parameters, systematize spacetime/coordinate/parameter names (there is a perl script in par/convert-pars.pl to convert old parameter files to the new names) * [from Mitica Vulcanov] many additions and fixes to cosmological solutions and Schwarzschild-Lemaitre * fix stress-energy tensor computations so they work -- before they were all disabled in CVS (INCLUDES lines were commented out in interface.ccl) due to requiring excessive friendship with evolution thorns and/or public parameters; new code copies parameters to restricted grid scalars, which Cactus automagically "pushes" to friends * added some more tests to testsuite, though these don't yet work fully Additional internal changes: * rename many Fortran subroutines (and a few C ones too) so their names start with the thorn name to reduce the chances of name collisions with other thorns * move all metrics to subdirectory so the main source directory isn't so cluttered * move two files containing subroutines which were never called (they didn't belong in this thorn, but somehow got into cvs by accident) into new archive/ directory * some (small) improvements in efficiency -- the exact_model parameter is now decoded from a keyword (string) to an integer once at INITIAL, and that integer tested by the stress-energy tensor code, rather than requiring a separate series of string tests at each grid point (!) like the old stress-energy tensor code did git-svn-id: http://svn.einsteintoolkit.org/cactus/EinsteinInitialData/Exact/trunk@92 e296648e-0e4f-0410-bd07-d597d9acff87
