About basics code

[lelence]

hi, thanks for the code. I have one question, may I add a "namespace" in basics.cpp, like this:

namespace test {
class basics : public contract {...};
}
EOSIO_ABI( test::basics, (test) )

I know if the namespace is "eosio" it`s ok, but other characters , will create an empty abi file, how can I do.
