Fixed a typo
Renamed crontimer to cronparser

The new name better reflects my goals for this project
Moved most of parse_range tests to unittest

I'm not thrilled with unittest at this point either, though. It feels
a bit more heavyweight than I'm looking for. I also added an __eq__
function to Range for testing purposes.
Copied parse_set tests to test_parser

Copied for now since there's only one and I'd like to keep the doctests
having a usage example. Also I made it so that the unittests call the
parser.py's doctests to eventually have all the tests runnable with one
command. Also I actually added test_parser.py to the git repository,
which I forgot last time... The perils of late-night commits.
Changed the _RANGE constants to an Enum

Have I mentioned that I love the recent additions to the python standard
library? I think they've done a great job with them. When I deploy them
to PyPI I might want to change this to just a class for compatability
with older versions of Python, unfortunately.
Created test_parse_job

With one test. I have some other improvements in mind, but I'm going
to move the crontab functions to a new file before I make any changes
in that regard.
Renamed test_parser to tests

I realized that there aren't enough tests at the moment to justify
having them in two separate files. I might revert this change eventually
though.
Converted Range tests + improved fuzzer

I made the fuzzer generate more useful tests after noticing that when I
made the asserts fail by adding one to the step, they were mostly
failing because the carry was different. So I made the bound minimum and
the step both tend towards smaller numbers.
Reordered the tests

So they match the order they appear in the source.
Put space in doctest for PEP 8 compliance

My checker doesn't check doctests, so it slipped through the cracks.
This is one of the major reasons that I'm moving the majority of my
tests to unittest over doctest and leaving my doctests as usage
guidelines.
Finished moving tests over to unittest.

Finally time to start doing more meaningful changes
Improved doctest integration

Also tweaked how tests are loaded. To run the test suite either call
python3 -m unittest or run python3 tests.py
