constructor takes a keyword table, so it can be used for arbitrary DSN
syntax files of your own chosing. Simply create an enum {} with all your
unique tokens in it. Then create a KEYWORD table. See SPECCTRA_DB::keywords[].
The reason you want an enum is to give the C++ debugger better type information
so it can show symbolic integer symbols.
* Factored out common richio.cpp and richio.h
which is what DSNLEXER uses.
* Fixed some minor issues with reading circuit descriptor from a *.dsn file.
* Moved ReturnLayerName() to static BOARD::GetDefaultLayerName() and migrated
to a Specctra DSN compatible default layer naming scheme:
Component becomes Front, Copper becomes Back.
* set_color.h: Cmp becomes Front, Cu becomes Back.
* D_PAD::DisplayInfo() changed to use actual copper layer names.
* more layer setup dialog work, moved all programmatic wxControl instantiation
into the wxFormbuilder environment, but this is fraught with danger:
wxFlexGridSizer used the tallest control to establish the row heights, so
be careful about changing control borders in the scroll panel. The vertical
size can explode since just a couple of pixels times the number of rows
is substantial. Currently I am setting a 5 pixel border only left, top, and right
but not bottom.
* Set copper layer count is back in place as a hack until I can get the enabled
layer bit map fully operational.
