Cartographer points you at the maps

In particular, cartographer lists all source locations in a package which are loops over maps. If you're not careful, these may cause your program to be non-deterministic.

Example of use

go get -u github.com/pwaller/cartographer

$ cartographer github.com/pwaller/cartographer/example
/home/pwaller/.local/src/github.com/pwaller/cartographer/example/main.go:7:2
/home/pwaller/.local/src/github.com/pwaller/cartographer/example/main.go:10:2
/home/pwaller/.local/src/github.com/pwaller/cartographer/example/main.go:14:2
/home/pwaller/.local/src/github.com/pwaller/cartographer/example/main.go:17:2
/home/pwaller/.local/src/github.com/pwaller/cartographer/example/main.go:20:2

    A >7,000 line code base was emitting things in an arbitrary order, which made diffing the output difficult.

Thanks

To @JohannesEbke for hacking on the earliest prototype together.
