commit, mostly relating to the scale of values in the ".nodes" file
produced by ext2sim. Making this file CIF syntax seemed unnecessary,
so I removed the CIF syntax and scaling. "extresist" can now produce
an apparently valid output on a standard cell layout. Even with the
change, the extresist output is still only pseudo-hierarchical, so
this does not preclude the need for eliminating the .sim format file
in favor of the .ext file, but it provides a working intermediate
form.
