Minor tweaks

  Working on OpenCL support

  Working on OpenCL runtime

  Added name to world structure in OpenCL runtime.  Also added more error
  checking to Diderot_LoadSource.

  OpenCL hacking

  Use the program name as the default output file name.

  Fix bug in the stabilization of strands

  Added timing support and fixed a build typo

  Fixed unclosed comment

  Added target defines to CPPFLAGS

  Working on OpenCL support

Commiting OpenCL implementation does not include Diderot library functions support

  Working on OpenCL runtime support.  Also, added configure support for generating OpenCL
  runtime makefiles.

  expand tabs to avoid editor differences

  Start of runtime support for OpenCL

  Adding support for command-line arguments

  Working on command-line option support

adding more comments, and cosmetic tweaks

incomplete commit of the previous bugfix

fixed hest-related memory bug triggered anytime that struct Diderot_Options_s's optDef_t *odef array had to be re-allocated. Basically: you can't give hest a pointer (to store a variable in) that points into an array that might be reallocated later, since the reallocation will end up at a different address

working implementation of hest wrappers for command-line arguments

  Reclaim space for option descriptors

  Added hest wrappers

  Split input functions into their own file and added Diderot_InputVec2

  Use atomic add to update numActive

  Working on support for parallel runtime

  Working on parallel runtime

  Use double precision to compute transforms for images.  We then convert these to the
  target precision.

  Fix cleanup

  Working on parallel runtime

  Add parallel runtime support

  Port eignevalue stuff to diderot runtime

  Working on porting eigenvector code to Diderot runtime conventions

  Working on multiple-target support

  Better cleanup

  Runtime system updates to support Die and to eliminate race for stabilizing

  Fix syntax error

  Some runtime system changes

  One more -m64 fix

  More work on runtime build infrastructure

  Working on new runtime build infrastructure

  After strand initialization, we copy the initial state into the other state
  object so that invariant state variables have the correct value in both
  copies.

  Reworked representation of coordinate-space transforms in image objects

  Fixed typo in Makefile.in

  Tweak error checking on image files

  Be more tolerant when checking the kinds of the axes.

  Added some consistency checking to image loading routines.

  More adjustments for non-scalar images

  bug fix to runtime: account for voxel dimensions when loading transform matrices

  Simplify matrix loading code

  Adding support for loading 1D image data

  Update INSTALL instructions

  Adding 3x3 matrix and 2D image support

  Added -m64 flag to C compiles and fixed some warnings.

  Added support for tracking output state variables through ILs and generating
  a print function in the C target.

  print range of results for debugging

  bug fix: out and in were backwards

  Switch to compiler-generated initially code.

  Added runtime interface to support creation of initial array/collection
  of strands

  Don't map negative values to 0

  modified debug printing

  Minor code cleanup/fixes

  Fixing bugs in runtime code

  Debugging vr-MIP code

  Working on vr-MIP example

  Add support for building runtime library to top-level makefile

  Working on Diderot runtime

  Working on build scripts for Diderot test programs

  Move diderot.h header to include/Diderot

  Minor edit

  Working on header

  Creating a branch to explore a pure CFG IL

  Added comments about SSE

  Working on C version of MIP

  Add Diderot_Mat types

  added InvertTranspose operation

  Bug fix: change + to *
