Allow printing a Variables object

The Variables object has been somewhat opague - kind of hard to tell
what you got. This adds as __str__ method which produces a formatted
string showing the contents of the object, so debugging can do:

var = Variables()
... bunch of setup stuff
print(var)

and get a reasonably readable representation.
