Matt Guthaus 946a0aca86 Simplify DRC and LVS run scripts. 
Modified run scripts to work on local only files in the temp
directory. This assumes the files and subckts are named the
same as the clel name. Script now copies library files
to the temp directory as well.

shapes to keep things connected.
