Log Message:
this is a much-updated version of CADlib. some needed functions were added for
manipulating UG. much of it has been converted to STL, although not yet all of it--
in particular many char arrays were replaced with strings, as these were causing a
problem.

the relevant code from support/ was brought here, and some of it was removed
(in particular the list code). h_table is still used.

StringPack is used to group together and serialize named values in a
forward-compatible manner. that is, one can add values to a StringPack object, and
as long as the keys (i.e. names) are different, they will not interfere with other
values. the serialized strings produced are UG-compatible, so they can, for instance,
be used in vertex names. right now only strings, ints, and doubles are supported as
values (and the keys are always strings).
