so the options hash can be easily passed to Rails form builder methods.

1. Runs Primer's classify routine to convert entries like mb: 1 to mb-1.

This method does the following: 
def classify(options)
  options[:classes] = class_names(options.delete(:class), options[:classes])
  options.merge!(Primer::Classify.call(options))
  options.except!(*PRIMER_UTILITY_KEYS)
  options[:class] = class_names(options[:class], options.delete(:classes))
  options
end
