rails statistics hacked to get gross LOC of Views, css, js, coffeescript, RSpec and cucumber

stats.rake

# Note THIS IS some hackety hack code without tests. CodeStatistics class could be rewritten to be more configurable ...
task :stats => [:statsetup, :stats_assets]

# Setup specs / cuke & js for stats
task :statsetup do
  require 'code_statistics'

  class CodeStatistics
    alias calculate_statistics_orig calculate_statistics

    def calculate_statistics
      @pairs.inject({}) do |stats, pair|
        if 3 == pair.size
          stats[pair.first] = calculate_directory_statistics(pair[1], pair[2]); stats
        else
          stats[pair.first] = calculate_directory_statistics(pair.last); stats
