/ccProcessor
this is a credit card processor that uses luhn10 to verify cc number and
process methods as they are called off from a text file
the /cmd dir has the Command Pattern version; a refactor from a terser hack
that used ruby's dynamic capabilities, essentially self.send. A labor
of love to help remember why patterns are important
/cmd
Client = credit_card_client.rb
Invoker = credit_card_processor.rb
Receiver = credit_card.rb
Cmds = charge_command.rb, credit_command.rb
/game
lexicon.rb:
This is an improved lexicon from "Learning Ruby The Hard Way".
The mixed hash access in ruby allows for a much more terse version.
game.rb:
This is funny game from "Learning Ruby The Hard Way" that I put into
separate files as an exercise in dynamic methods and ruby OO. I plan
to turn it into a different game eventually.
/test
test_lexicon.rb:
A test for Lexicon.scan().

/floor_division
This is a first attempt at integer division without the '/' operator.
It uses binary search. I kept the methods public because I wanted to test them.
integer_divsion.rb
several useful methods besides floor division
test_integer_division.rb
lots of tests for all the methods
