Merge pull request #7 from AidanDelaney/master

Added the ratio of TBox:ABox:RBox as a metric.
Updates to open cleanly on new Eclipse

Various classpath updates to open and build properly on a newly
installed Eclipse under Mac OS X 10.9.
Fixed and renamed AnnotationsRatio plugin (from now on CommentsRatio).
Consistency update
Reversed prior classpath settings

So apparently my Eclipse is acting up real weird, and returning the
settings to what they were prior to my previous commit solves this
issue. Sorry about the flaky previous commit.
