Merge pull request #26 from tansaku/migration_grader

Migration grader
Update README.mkdn
Fixed an issue with coverage reports due to load order of graders in auto_grader.rb. Added Normalize text in grade.rb. Increased timeout in run_with_timeout as I had some tests occasionally fail. Also added NoSuchSpecError tests to rspec_grader and weighted_rspec_grader spec files.
Moved hw5_grader.rb loading after heroku_rspec_grader.rb because of inheritence in auto_grader.rb
Added test for invalid initialization
Stubbed out file system for spec
Completed tests for initialize method
Initial commit of Feature Grader acceptance tests
starting on acceptance test for feature grader
changed cuke kstep to have feature and step definition files
Added some steps to create necessary files
Passing cucumber feature: Feature Grader and scenario: Simple Mutation Test, but getting invalid cucumber results.
automating a bit more of the feature grader setup and realizing we need a consolidation of the grader scripts to make progress - failing rspec for new_grader with feature grader args
oops needed a -a flag as well
started on acceptance test for command line feature and some refactoring of same
using regex to make feature pass
