mrg 5e546ee974 New power strapping mostly working. 
Each module uses M3/M4 power straps with pins on the ends.
Works in all technologies for a single no mux, dual port SRAM.

mrg d609e4ea04 Reimplement trim options (except on unit tests). 
Allow trim netlist to be used for delay and functional simulation.
Each class implements a "trim_insts" set of instances that can be removed.
By default far left, right, top and bottom cells in the bitcell arrays are kept.

Use lvs option in sp_write

Fix lvs option in sram.

mrg c472a94f1e Rework bitcells. 
Name them 1port and 2port consistently.
Allow cell overrides to cell_1rw and cell_2rw or other.
Will use 2rw for 1rw/1r, 2rw, 1w/1r, etc.

Bastian Koppelmann dd1afe0313 Bitcell arrays: Allow mirroring on the y axis 
this allows for bitcells that need to be mirrored on the y axis, like
thin cells. However, the portdata elements also need to be mirrored on
the y axis. Otherwise the router will fail horribly when connecting
bitlines.

Bastian Koppelmann 3fb2b9c1c3 Bitcell arrays: Create abstract base class 
a lot of functions of dummy- and bitcell-array are either copy-pasted or
have just slight differences. Merge all of those into an abstract base
class such that we don't have too much duplicate code.

Matt Guthaus ed28b4983b Clean up and generalize layer rules. 
Convert metalN to mN.
Generalize helper constants in modules for
space, width, enclose, etc.
Use layer stacks whever possible.
Try to remove drc() calls in liu of helper constants.
