Elle Microstructural Modelling SVN Code

problem reassigning unodes, showed up on Win32

don't include ppm.h

elle2poly does topology test after reading tmp.elle.
Need to rewrite tmp.elle in case topology has changed,
else basil2elle will be confused

add read image fn

image read fn declaration

elle.tmpl - remove netpbm
install.sh - gpc dir copied because ln -s doesn't work on win32

xpak.c, cmndefs.h - just a bit of code to generate the elleX colourmap
- commented out
lppak.f, sybilps.parameters - first rule of mixed language programming:
function names (and parameters) should not have '_'!

misorient.cc: fix code calling Log
tripoly.c: only write poly file if debugging
runopts.cc: make sure ElleSetDisplay(0) for batch mode
Imakefile: add image.c to srcs and link into batch and X base lib

Code to read ppm file. Very basic.

Removed need for netpbm lib
Changed so that GUI versions allow user to open image file which is then
converted. Data kept in memory til user saves. Free memory so several
files can be converted and saved before closing app.
