Split examples into separate markdown files, each containing a description, sample code, and a screenshot of the resulting xlsx document.

The script `generate.rb` is provided to actually generate the example documents by executing the sample code contained in the markdown files.

+wb.add_worksheet(name: 'Second Worksheet') do |sheet|
