build a SQL database during liberty parsing
added special input and output tables
added sql netlist parsing (and other stuff, oops)
properly generates an sql database, but slow as balls
build sqlite3 database from lib parsing
now properly accesses the sqlite database
added cell name to type map and pin direction map
added wire remover code and turned fk_id column into lpid/gid column
removed cruft
removed class crap, for a clean sql head
now assuming single module declarations
removed db connection stuff
now using gate_type class for liberty parsing
liberty gate type parsing complete
netlist parsing now uses simplified gate class
wrote wire_remover, not tested
got parsing and wire replacement to work
fixed some wire removing error (from assign stmts) and move netlist.py into classes.py
i think wire removal now really works?
