  # HashWithCssStyleKeys is solely for being able to access a hash
  # which has css-style keys (e.g. 'font-size') with the underscore
  # symbol version
  # @example
  #   opts = {'font-size' => '23px', :color => 'white'}
  #   opts = HashWithCssStyleKeys[opts]
  #   opts[:font_size]   # ===> '23px'
  #   opts[:color]       # ===> 'white'
