add cucumber to gemspec as development dependency
add rspec to dependencies (using only expectations for now)
Add Cucumber feature for single dice rolling
add Cucumber to Rakefile (in preperation for CI)
add .travis.yml to project
fix up .travis.yml
add Travis build status to README
minor grammer corrections in simple_dice.feature
step 0: add scaffolding for existing cucumber steps
add test code for given dice function

step 1: gotta be hardcore
think using RpgDiceRoller::Dice is better anyway
finish cucumber step 1 - initalizing dice (could use another feature here)
cucumber feature 2 done (intentionally with simple number returned)
finish cucumber steps for simple dice roller, ready to test
Merge branch 'initcucumber' into testing - code there ready for CI
Add basic documentation to the program.
Add rdoc generator to Rakefile + update gemspec

html directory (where rdoc was generated) added to .gitignore as well
Add more RDoc documentation to dice.rb
tab in gemspec likely shouldn't be there
update README
