Tool to compute simple checksum.

I needed a way to compute a very simple checksum, that could also be done
by hand if needed. This is for my library catalog system.
Added Boilerplate module.

Tired of doing the same dance for argparse, logging, and config files.
This module abstracts all of that away behind a nice clean object.
Added illustration of adding argument.

This shows how easy it is to add options and arguments to new programs.

Config file junk to follow.
Converted cksum to use Boilerplate.

Now, things should be easier to manage.
Output will not have spaces.

The finished checksums should be blocks with two characters and a number,
with no spaces. If there is only one character, things will probably blow
up, but I'll figure that out later.
Fixed several bugs and finished program.
Added the ability to read environment vars.

Now, any command option can have an environment variable default. So, for
program foo.py and option bar, use boilerplate.EnvironmentDefault, and set
FOOPY_BAR=baz to get the effect of --bar=baz in foo.py.
Added a sample rc file to show it works.
Removed files that are not related.
This is a real package now.
Added some docs.
Perhaps I used the wrong extension?
Fleshed out README.
Merge c:/Users/tokuc_000/Projects/Boilerplate
Renamed README.
