fixing the rspec grader spec so that it runs with current layout
adding spec for weighted rspec grader
added term-ansicolor to Gemfile to get majority of failing tests passing - CourseraClient spec still fialing, but looks like it needs django auth which is maybe no longer relevant?
one grader to rule them all and in the darkness bind them
Add markdown formatting to README

Merge pull request #1 from mateor/master

Change README to mkdn
spec driving the new grader forward - stuck on speccing instance variables
Merge branch 'master' of github.com:tansaku/rag-saasbook
Merge remote-tracking branch 'upstream/master'

adding travis C.I. support
sticking with ruby 1.9.3 for travis
