In preparation for making a `Location` type to represent world locations.
It had `loc` and `north` swapped, so `initRobot` was always creating robots at location `(0,1)` with a *direction vector* given by whatever the location was supposed to be, which makes no sense. Now that `Location` and `Heading` are distinct types, this became a type error.
Still need to add `meetAll`, and create a device that provides `meet` capability.
Closes #931.
We may also use it for other things in the future.
