Working on 'info object *' ensemble
Done with 'info method *' ensemble
Some polishing of Object.man
- minor cleanup
- simplify slot parameter settings for object-mixins and object-filter lightly by omitting redundant methodname
- updated documentation
- updated TODOs
nx.tcl
- drop short form "/obj/ info configure" for now
- make output of "/obj/ info lookup configure syntax" equivalent to
  "/obj/ info configure"
- also drop class level "info configure"
Done with first version of Class.man
Merge branch 'master' of ssh://alice.wu-wien.ac.at/usr/local/src/git-repo/nsf
gentclAPI.tcl:
- handle duplicated domains by folding these to a single definition

nsf.c:
- added command nsf::method::get.
  Rationale: provide a central place to obtain information
  about all kind of method handles, which might be
   - scripted and c-based methods
   - nsf::procs
   - plain tcl procs
   - cmds (with and without paramter definitions)
- make results of ListMethod() robust against missing
  information (e.g. plain tcl cmds, missing object registrations,
  etc.)
- factor out common code for ListMethod call sites
  for per-object methods, instance methods and procs/cmds
  to ListMethodResolve()
- return errors from failing converter registrations
- extend regression test (new test set nsf-method.test)
Merge branch 'master' of ssh://alice.wu-wien.ac.at/usr/local/src/git-repo/nsf
- update TODO
nsf.c
- renamed parameter::get -> parameter::info
- renamed method::get -> cmd::info
nsf.c, gentclAPI.tcl:
- new argument types "virtualobjectargs" and "virtualclassargs" for
  context-specific argument resolutions: when a context object
  is provided, arguments of type "virtualobjectargs" are determined
  based on the slots applicable for the object (like "... lookup ..."),
  arguments of type "virtualclassargs" are resolved against a class.
  These types are used as follows:
    /obj/ configure /virtualobjectargs/
    /cls/ create /name/ /virtualclassargs/
    /cls/ recreate /name/ /virtualclassargs/
    /cls/ new ?-childof /obj/? /virtualclassargs/
  This new feature allows us to provide better error messages and
  to make much of the "... info ... configure parameter ..."
  infrastructure much less important.
- For "virtualclassargs" we need the functionality to obtain
  from the C-Code based on a class the configure parameters
  applicable to objects of this class.
- add argument "-context ..." to "cmd::info" to pass the context object
  (so far the only place where the context-object is used)
- object system configuration parameters changes:
    new: -class.configureparameter
    new: -object.configureparameter
    removed: -class.objectparameter
- improve error message
- white-space change
- remove dead code
nsf.c:
- added options to filter output from ::nsf::cmd::info parameter options
  (args, syntax, parameter)
- deleted:
    - "/obj/ info lookup configure parameters ?pattern?"
    - "/obj/ info lookup configure syntax"
- added:
    - "/obj/ info lookup parameters /methodName/ ?pattern?"
    - "/obj/ info lookup syntax /methodName/ ?pattern?"
  This covers as well
    - "/obj/ info lookup parameters configure|create|new|... ?pattern?"
- extend regression test
