Doxygen filter changes * allow doxygen to process applications/**.H * use @cond/@endcond to suppress documenting classes/variables in applications/

 - allows some access from applications to libraries
 - connection between application and local includes is still a bit weak,
   but is possible via the dirs.html navigation.

Tried to sort out the scripts in the tutorials but found it is messed up.  Will start again from a new version from Mattijs

NamedEnum (bug in compiler?)
molecule (Graham dealing with it)
lex (no comment)
VTK (again no comment)

specifically on the request of the user by running 'wmake all' or 'Allwmake'
in the directory as appropriate.

  * skip doxygen docs for local variables (treeBoundBox)
  * filter transforms 'Typedef' -> @typedef
  * added tools/find-retagged
  * manually changed some InClass tags to Typedef - still needs more attention

Application
    expandDictionary

Description
    Read the dictionary provided as an argument, expand the macros etc. and
    write the resulting dictionary to standard output.

* Now that the expansion of FOAM_CASE is delayed in the boundary conditions,
  the old expansion is simpler and seems to work better with IOobjects.
