[Rprotobuf-yada] start to play with proto files

[Romain François]

This is too much fun ... and good excuse to learn some C++

I've commited some code in the readProtoFiles. Nothing too fancy for the 
moment, just reading a proto file and grab some information from it:

$ r -lRProtoBuf -e "RProtoBuf:::readProtoFiles()"
<readProtoFile>
[1] "/tmp/person.proto"
    importer.Import( '/tmp/person.proto' )
   name    = /tmp/person.proto
   package = tutorial
   number of top level message types = 2
        0  : tutorial.Person
        1  : tutorial.AddressBook
   number of top level enum types = 0
</readProtoFile>
