1. Parser improvements

Browse Source 
a) const and virtual methods are parsed correctly (not static yet)
 b) "const" which is part of the return type is not swallowed

2. HelpGen improvements: -o outputdir parameter added to the cmd line,
   "//---------" kind comments discarded now.

TODO (+ means fixed)
(i) small fixes in the current version
+1. Quote special TeX characters like '&' and '_' (=> derive from wxFile)
2. Document typedefs
3. Document global variables

(ii) plans for version 2
1. Use wxTextFile for direct file access to avoid one scan method problems
2. Use command line parsrer class for the options
