Uncaught Error: Could not resolve .FOO

See https://developers.google.com/protocol-buffers/docs/proto#packages-and-name-resolution:

Type name resolution in the protocol buffer language works like C++: first the innermost scope is searched, then the next-innermost, and so on, with each package considered to be "inner" to its parent package. A leading '.' (for example, .foo.bar.Baz) means to start from the outermost scope instead.
