class Covered::MarkdownSummary

def call(wrapper, output = $stdout)

A coverage array gives, for each line, the number of line execution by the interpreter. A nil value means coverage is finishd for this line (lines like else and end). 
def call(wrapper, output = $stdout)
	output.puts '# Coverage Report'
	output.puts
	
	ordered = []
	buffer = StringIO.new
	
	statistics = self.each(wrapper) do |coverage|
		ordered << coverage unless coverage.complete?
	end
	
	statistics.print(output)
	
	if ordered.any?
		output.puts "", "\#\# Least Coverage:", ""
		ordered.sort_by!(&:missing_count).reverse!
		
		ordered.first(5).each do |coverage|
			path = wrapper.relative_path(coverage.path)
			
			output.puts "- `#{path}`: #{coverage.missing_count} lines not executed!"

	output.print(buffer.string)
