Getting this thing a bunch closer to functioning
Trying out a new test output style
Updating dep. for improved test suite
Fixing calculation of maximum iterations
Foregoing `gets` where `return` is sufficient
Fixing bug where search would terminate far too early

I wasn't passing forward the current coordinate for the search....

Derp!
Updating dep. version
Whoops, including unchecked-in import
Fixing a bug where only half of the breadcrumbs were being displayed

Coincident with this change is a slight refactoring to not thread the
fresh location through the call stack, and, instead, put the location
into the state of the computation, where it really ought to be.

This was the final bug that I'm aware of in this project.  Hooray!
Updating readme to be less self-loathing
1.0 release!
