done not needed clang doesn't use exceptions create a class to test exception with bad file
done finish HeaderParser(), addSourceFile and addSearchPath
done create an inline initializeCompilerInstance
done set clang::InitializePreprocessor (line 99 in gears.cpp) in parse method
done remove gears.h , .cpp
done continue test default constructor
done test with args constructor
done full test of parsing
done add tests  for EnumConstant, Parameter, Field
done add tests for Type
done remove getInternalTypePtr test and the others
done see for pb isCanonical see mail and const RecordType * getAsStructureType() const then TagDecl * getDecl() const
done create a method in order to get the represented clang class (getInternalClangTypeClassName() )
done find all the QualType methods that returns another QualType
done add isMain() method to Function class
done update swig lib
done add option to force parsing on only main file:
TODO update interface for Parameter and Field
  *    done remove getParameters
  *    done remove getFields
  *    done remove getConstants
TODO try to get global variables
TODO find a way in order to get Decl from typedef -> Type

and http://www.ibm.com/developerworks/linux/library/os-createcompilerllvm2/index.html?ca=drs-#list15
  where to do specify it ?
    HeaderParser constructor with default langage C
    HeaderParser::parse(std::string langage)
