This directory contains the interpolator registered for
   CCTK_InterpLocalUniform()
under the name
   "generalized polynomial interpolation"

This interpolator is distributed under the GNU GPL; see the file COPYRIGHT
for details.  Note that this means that if you distribute any program
using this interpolator, you must provide source code to the entire
program!



To add a new combination of (N_dims, molecule_family, order, smoothing),
to this interpolator, you need to
* edit the appropriate Maple script (1d.maple, 2d.maple, 3d.maple, etc)
  to generate the coefficients and write the appropriate files
* edit the makefile to create the appropriate directory or directories,
  and if necessary add any new targets
* 'make' as appropriate to create the new coefficients etc
  [note this can be rather computationally intensive -- the current
  set of {1d,2d,3d} coefficients take {4 seconds, 15 seconds, 8 minutes}
  to generate using Maple 7 on a xeon (1.7 GHz Pentium 4)]
* edit InterpLocalUniform.c to add the new case to the decoding
  switch statements
* create an appropriate "script" file which defines the right macros,
  then does a
	#include "template.c"
  to define the actual interpolation function; the best way to create
  the script file is just to copy an existing one
  (eg. 2d.cube.order3.smooth0.c)
* add the appropriate entry to all-prototypes.h to define a prototype
  for the actual interpolation function
* add the new "script" file to the list in make.code.defn



Other makefile targets:
test_molecule_posn
	This makes a standalone test driver for the
	   LocalInterp_molecule_posn()
	function defined in molecule_posn.c
