Removed all of the routines that generate compiled libraries from
individual files for various file formats (GDS, LEF, SPICE/CDL,
and verilog (liberty is unfinished and probably never will be), and
put the in individual files that can be either run separately from
the command line or included into the foundry_install.py script and
run internally.
