# The discover method defines the following keys as appropriate:
# :ruby a string array of discovered require statements
# for example,
# given rb file containing
#   require 'json'
#   require 'yaml'
# the resulting dependies would be
# dep[:ruby]=['json','yaml']
#
# C# dependencies are returned as a hash, as they are seperated into 
# two groups, :system and :file
# 
#
class Dependencies < Hash
