Translate the arguments of genreflex into rootcling ones and forward them to the RootCling function.

These are two typical genreflex and rootcling commandlines 1) genreflex header1.h [header2.h ...] [options] [preprocessor options] 2) rootcling [-v] [-v0-4] [-f] [out.cxx] [-s sharedlib.so] [-m pcmfilename] header1.h[{+,-}][!] ..headerN.h[{+,-}][!] [{LinkDef.h,selectionRules.xml}] The rules with which the arguments are translated are (1st column genreflex): –debug -v4 –quiet -v0 -o ofile positional arg after -f -s selection file Last argument of the call –fail_on_warning Wrap ROOT::TMetaUtils::Warning and throw if selected

New arguments: -l –library targetLib name (new) -s targetLib name -m pcmname (can be many -m) (new) -m pcmname (can be many -m) –rootmap -rmf (new) –rootmap-lib -rml (new)

genreflex options which rise warnings (feedback is desirable) –no_membertypedefs (it should be irrelevant) –no_templatetypedefs (it should be irrelevant)

genreflex options which are ignored (know for sure they are not needed) –pool, –dataonly –interpreteronly –gccxml{path,opt,post}

Exceptions The –deep option of genreflex is passed as function parameter to rootcling since it's not needed at the moment there.
