int configGenerator::genConfig	(	const Strings_t &	modules,

main entry point of this class:

iterate over all the modules (ie: library names)
for each module extract component informations
eventually generate the header/body/trailer python file and "Db" file

not enough information... skip it

no Properties, so don't bother create Configurables...

write-out files for this library
