Add trunk to ellipsis3d.
Add the ellipsis3d code.  Very rough, needs to be cleaned up, and 
probably hard to build.
Add the shell scripts (whoops).
Added GNU build system.
Cleaning.
Removed extra directory level ("Source_code");
nuked "Shell_scripts".
Added comments about how "module" #includes were
originally generated.
Added standard GNU info files.  "ChangeLog" generated with
svn2cl (http://ch.tudelft.nl/~arthur/svn2cl/)
using the following command:

svn log --xml --verbose | xsltproc --stringparam strip-prefix mc/3D/ellipsis3d/trunk --stringparam include-rev yes svn2cl.xsl - > ChangeLog
Added subminor to version; added svn:keywords.
Changed my mind about ChangeLog, and cApS.  Now generate

svn log --xml | xsltproc --stringparam include-rev yes svn2cl.xsl - > ChangeLog
