@JesseyWright I have added a couple of full-examples. Please have a look. Still working on this interface, but I could use some help writing more of those:

first, some commands preceded with >>> , which get you to a certain state.
second, call interface_object.cmdline
third, a string that will be tested against the outcome of calculating the command line in the current state.

sorry for the short message, writing from SFO.

@JesseyWright I've finished the inputs and their tests. I believe this should be functional. However, this will fail when composing the outputs - could you find some data to test this on?

This pull request is "orphaned," which means it has been deemed to be abandoned by its original author. Orphaned pull requests have not been rejected, and we hope that if a user sees one that will meet their needs with a little work, that they will fork it and open a new pull request (or, in the case of the original author, reopen the original PR).

We ask that all adopted PRs be updated to merge or rebase the current master. If you would like to adopt a PR and need help getting started, any of a number of contributors will be happy to help.
