1) Corrected spurious error messages about cells already existing in GDS when using "flatten" or "flatglob". 2) Fixed handling of resistance as a subcircuit parameter 3) Added area and perimeter resistance for a device; this is done through the "devresist" statement in the tech file, which is an extension of the original "fetresist" statement. Where "fetresist" only supported type "linear", "devresist" supports types "area" and "perimeter". 4) Support for CDL syntax, including generating subcircuit-like parameters for components starting with SPICE-standard prefixes like M, R, C, etc., adding "/" between pins and subcircuit name, and saving the file as ".cdl" instead of ".spice". 5) Estimated L and W for devices whose geometry is complex and do not reduce to a simple rectangle. L and W are estimated as the square root of the area. 6) Changed the method of extracting L and W for diodes to use the same method as capacitors. Note that diodes are not usually specified by L and W, but if they are, this will produce the right result. 7) Corrected the reported filename and line number when printing error messages related to errors inside a technology file, when the technology file uses "include" to combine multiple files.
