* added macro processor skeleton
* added "savemacro" option, which saves the result of macro expansion in a file named "filename-macroexp.mod"; this file can be fed back to Dynare
* implemented @include directive; note that nested includes are possible; error messages in Dynare pre-processor will point to the filename effectively edited by the user
* split DynareMain.cc in two files, because of a Bison restriction: it is impossible to include both MacroDriver.hh and ParsingDriver.hh from the same source file
