Add an Inspect or String method for reflect values that prints Values the way the are entered in Go.

This is probably a flaw in the reflect value, but "%v" seems to display values slightly different than as you would in entering them into go.

In particular, %v gives <nil> instead of nil. And strings aren't quoted, and probably maps and slices values appear differently.

With commit 8eb5c0f I have started to address this.
