Overhaul of the hash table method. Original method used global variables to iterate over hash table contents. This led to the inability to nest hash table iterators. Fixed by defining a wrapper structure that holds the actual hash table plus the size and iterator indexes. Not only does this solve the nesting problem, but it also avoids the need to pass the hash table size on every call, and that reduces the number of ways a hash table subroutine can go wrong (e.g., cannot access the table out of bounds simply by passing a size that is larger than was used to initialize the table).

Corrected the "property tolerance" command in tclnetgen, and cleaned up some of the property matching output.

Extended the prematching phase to include matching of devices based on properties that can be traded with number of devices, such as MOSFET width, by merging. This initial implementation is somewhat limited, only dealing with properties that merge by summing. Only devices that do not match at all in the other circuit will be considered for merging. The feature includes a command option "property ... merge ..." that allows control over which devices can and cannot be merged.

Finished basic implementation of matching device properties to include calculations of effective width due to the addition of width of multiple device instances in parallel. The original behavior of splitting all "M=" devices into individual instances has been effectively inverted, instead combining all parallel devices of the same class into one, with multiple property records for devices with non-matching properties (e.g., width, length, etc.). Property matching combines devices with different "critical properties" (e.g., FET gate width) if these are defined in the setup using the "property merge" command. Not yet done: Matching of multiple property records when critial properties are not defined, handling of critical properties that combine in parallel instead of simple addition, handling of devices that combine in series, and the combination of non-critical properties (e.g., source and drain area, although these are usually removed from matching).
