Error handling complete

This should be the last source-code update, unless something comes up or there is a new version of Rye between now and the next step on my roadmap (compiling to stand-alone executable).

Migrate to Rye v0.2.3

Nothing new, just migrated to Rye v0.2.3

Fully functional, just needs some error handling

This is, I hope, the last release before I go to 1.0.0. I was going to tag this one as 1.0.0, but realized that nothing should be tagged that way until there is some basic error handling in place.

Patch for compatibility with Rye 0.1.02

Between Rye 0.0.99 and 0.1.02 there have been numerous changes, some of which may affect how I write the code, but the change from to-upper to upper is the only breaking change I've found.

Initial release from stand-alone project repository

The only difference between this one and the one in jaderoca/Rye is that now it's a stand-alone project instead of just a learning exercise.
